Abstract
The present study aims to investigate the aggregate analysis of linguistic variables of South Ruedbar language varieties in Kerman province by using the dialectometry and mapping software package with a quantitative and holistic approach. Data collection has been done from 22 sites from the south seven cities of Kerman province. For this purpose, a questionnaire containing 208 words and 10 basic sentences based on ‘National Language Atlas Project Questionnaire of Iran’ and ‘Morris Swadesh basic list words’ are used. The validity of mentioned questionnaire was 0.98 based on Cronbach’s alpha test. The results of aggregate analysis showed that 6 major dialect clusters are distinct and these dialect clusters are divided into subclusters. Each of these dialect clusters has distinct phonetical, phonological, morphological, or syntactical features that set it apart from other clusters. Based on statistical analysis, the ‘A’ dialect cluster due to the use of the continuous prefix /mi-/ and plural suffix /-hɑ/ in comparison to other clusters has the highest similarity and the ‘B’ cluster in cases such as the use of the infinitive suffix /-eng/ and continuous suffix /-æ/ has the highest difference in terms of morphology and syntacticity with the standard Persian. The ‘J’, ‘D’, ‘H’ and ‘V’ dialect clusters despite their distinction from the standard Persian, as the use of the continuous prefix /-ʔæ/ and plural suffix /-on/, are most similar to Aeach other and in terms of phonetic process and the presence of South Ruedbar variety special phones are similar to ‘B’cluster.

Abstract
The Quranic word "raht" is associated with two semantic domains: kinship and community, and it encompasses various meanings. The present study seeks to address the issue of why the word "raht" has multiple meanings and what its primary meaning is. Commentators and linguists have not provided any answer to this issue. These meanings are believed to have originated from potential twin roots in the Afroasiatic language family and the reasons behind the polysemy of this word by examining the processes of semantic construction of the word, along with its usages in Arab culture. This will be achieved by utilizing historical sources and then analyzing the word in the context of relevant Quranic verses, using a descriptive-analytical method. In the end, it has been established that the origins of this word can be traced back to two possible root meanings in ancient languages, one related to "combining" and "hand" and the other associated with "digging." These meanings have evolved over time and have shaped the various interpretations of the word. The association of common concepts of "group" and "collective" in classical Arabic and genealogy texts is derived from the concurrent meanings of "combination" and "symbol of the hand" in one branch of the word's historical roots and Considering the historical and cultural context of this word and its usage in the context of Quranic verses, it becomes clear that "Raht" is the smallest group within a tribe, often associated with unity and cooperation in facing or dealing with turmoil and challenges.

Abstract
Sweet potato is one of the most important root crop worldwide. This study aimed to compare agro-morphological characteristics of four sweet potato varieties (Martina, Janja, Lučka, Purple Speclet) from organic farming with additional information about their genetic background. A total of 26 agro-morphological traits were evaluated during vegetation. Pre-grown seedlings were planted in organic fields during the 2021 growing season using the soil ridge cultivation method. The study showed significant differences between varieties in quantitative (except for the extent and intensity of anthocyanin colouration on abaxial veins) and qualitative traits (except for the number and length of primary shoots and internode diameter). The varieties Lučka and Martina proved to be significantly higher yielding compared to the other two varieties. The genetic background of the varieties was evaluated on 8 SSR loci using allele polymorphisms with a total number of 34 different alleles and an average polymorphic information content of 0.60. The favourable informativeness of the selected markers was confirmed by the global genetic diversity of 0.68. The assignment of each genotype to two genetic groups agrees well with the varietal distribution in the phylogenetic tree and the results of the analysis of the genetic structure (Martina/Janja and Lučka/Purple Speclet). The present study contributes to a better knowledge of the sweet potato varieties considered and their agro-morphological and genetic diversity.

Abstract
Various factors, such as temperature stress, dietary changes, and the entry of contaminants and infections into the hemolymph, are known to affect insect immune responses by altering hemocyte profiles. The research focused on the hemocyte profile, hemogram across all biological stages, and the morphological and frequency changes of hemocytes in third instar larvae exposed to temperature stress. Cucumber fruits infected with insect larvae were collected and brought to the laboratory, where third instar larvae were extracted from the fruit tissue. The hemolymph was then collected, and after staining with Giemsa solution, hemocytes were identified under a light microscope. The hemogram analysis included measurements of DHC, THC, blood volume, and AHC across all biological stages. In third instar larvae, plasmatocytes and granulocytes were the most abundant, comprising about 56% of the hemocyte population. In contrast, prohemocytes were most frequent in the first instar larvae, accounting for approximately 37%. THC was highest in third instar larvae, indicating a direct correlation between hemolymph volume and total hemocyte count. Temperature stress had a significant impact on hemocyte numbers. Heat stress, with temperatures up to 30 and 35 °C, led to a notable increase in total cell count, granulocytes, and plasmatocytes. Conversely, cold temperatures resulted in a decrease in prohemocytes, plasmatocytes, granulocytes, and the total cell count compared to the control group. Additionally, temperature stress induced hemocyte deformation, with plasmatocytes and granulocytes showing the most pronounced changes under heat stress, including torn cell walls and loss of cell contents at 35 ○C.

Abstract
Moisture damage in asphalt mixtures poses significant challenges to infrastructure durability, necessitating accurate modeling for effective mitigation strategies due to the complex nature of moisture susceptibility. Current tests, such as those utilizing general indicators like the indirect tensile strength ratio, examine moisture susceptibility in asphalt mixtures. However, these tests incur substantial costs and require considerable time. Therefore, this study aims to develop moisture susceptibility prediction models using Multi-Gene Genetic Programming (MGGP). The research utilized four types of aggregates (two limestone and two granite types) and eight different Performance Grade (PG) bitumen types. The modified Lottman test method (AASHTO T283) was employed for moisture susceptibility assessment, with samples subjected to specific conditioning protocols including vacuum saturation (13-67 kPa absolute pressure), freeze-thaw cycles (-18°C for 16 hours), and hot water conditioning (60°C for 24 hours). Indirect tensile strength tests were conducted under controlled loading conditions (2 Hz frequency, 0.1s loading time, 0.4s rest period) at 25°C. The dataset comprised 34 samples and 11 variables to predict two key indicators: Inflection Stripping Point (ISP) and Stripping Slope (SS). The MGGP model demonstrated remarkable performance in predicting both ISP and SS, achieving R2 values of 0.981 and 0.974 for the test data, respectively. Several crucial parameters were analyzed, including the apparent film thickness (AFT) calculated using aggregate specific surface area, permeability measured through falling head test method (ASTM PS 129-01), and surface free energy components. The surface energy analysis incorporated both cohesive free energy (CFE) and adhesive free energy (AFE), with special attention to the acid-base theory components: Lifshitz-van der Waals (LW), Lewis acid (Γ+), and Lewis base (Γ-) components. For ISP prediction, the MGGP model identified key variables including the ratio of base to acid surface free energy (SFE), asphalt-water adhesion (ΓAsphalt-Water), cohesive free energy (CFE), adhesive free energy (AFE), permeability of asphalt mixture (PAM), asphalt film thickness (AFT), and degree of saturation (DS). The model for SS prediction emphasized the importance of ΓAsphalt-Water, aggregate-water adhesion (ΓAggregate-Water), wettability, specific surface area (SSA), PAM, and DS. The study employed various performance metrics to evaluate the MGGP models. For ISP predictions, the model achieved RMSE, MSE, and MAE values of 5.228, 27.337, and 3.843, respectively. For SS predictions, these values were 0.294, 0.086, and 0.231, respectively, indicating high accuracy and low error rates. These results surpass those of previous studies employing traditional Genetic Programming (GP) methods, highlighting the potential of MGGP as a powerful tool in modeling asphalt moisture susceptibility. The practical implications of this research are significant for improving asphalt mixture durability, reducing maintenance costs, and enhancing road safety. Future research could focus on validating the models across a broader range of asphalt mixtures and environmental conditions.

Abstract
Aim and Introduction
Today, the environment is considered as one of the most important pillars of sustainable development, and the development of other economic and social sectors depends on its sustainability and proper functioning. Environmental pollution has become one of the main challenges of countries. Environmental health is currently one of the most critical concerns of people and officials round the world. Almost all managers and decision makers believe that this national wealth should be protected not only for the current generation but also for future generations, since the pollutants caused by industries are highly costly and detrimental to health.
Active industries are one of the main sources of environmental pollution. One of the necessary conditions for economic progress and the introduction of extensive structural changes in economic and technological fields is industrialization and industrial development. In the production process, using production inputs whose main source is the environment, in addition to desirable outputs such as consumer goods, undesirable outputs such as environmental pollutants are also produced. If the number of outputs is not controlled and disproportionate, the losses from undesirable outputs will be greater than the benefits of desirable products in such a way that damages to the environment would be irreparable and sustainable development less likely to be achieved.
One of the most important concerns related to industrialization is the effects and environmental consequences of industrial activities. Therefore, achieving the necessary solutions to control such consequences is vitally important. Minerals are essential for human survival, but their extraction and processing are not environmentally friendly practices which contribute to problems such as soil erosion, air and water pollution. On the other hand, mineral sector is one of the largest energy consumers which has active contribution to air pollution and global warming. The main purpose of this study is to investigate the economic effects of Gol Gohar mine in Sirjan. For this purpose, it is intended to determine the type and amount of pollutants released from this complex, and also to determine the amount of the green tax of the complex as a solution to reduce pollution and examine the social welfare resulting from reducing pollution.
Methodology
In this study, the economic effects of environmental pollutants of Gol Gohar Iron Mine in Sirjan (Southeastern Iran), is investigated using the input distance function model from 2001 to 2022. Through calculating the shadow price of pollutants, a criterion for determining the green tax is determined, and then the amount of social cost resulting from the emission of pollutants is calculated.
The shadow price of the undesirable output is the cost that the producer must bear if they plan to reduce the production of the undesirable output. In fact, it can be interpreted as the marginal cost of reducing pollution for each producer. Therefore, the shadow price of the desirable output is considered positive and equal to the market price of that output, but the shadow price of the undesirable output must be estimated to be less than zero.
Findings
The products of Gol Gohar Iron Ore Complex in Sirjan, include granulated iron ore, iron ore concentrate and pelletized in the production process. The most greenhouse gases and air pollutants are related to carbon dioxide (CO2), sulfur oxides (Sox), nitrogen oxides (Nox) and particulate matter (SPM). According to the obtained results, the average shadow price for air pollutants in Gol Gohar complex for CO2, Sox Nox, and SPM was calculated as 11.15, 3,074.5, 5,529.62, and 1,875.62 rials per kilogram respectively. Moreover, the average total social costs resulting from the production of Gol Gohar Sirjan Complex was calculated as 92,710 billion Rials according to the amount of pollution produced over the period.
Discussion and Conclusion
The estimation of environmental costs is actually an introduction to providing solutions for internalizing and reducing environmental costs, using the input distance function model and the shadow price of environmental pollutants in the industrial and mineral complex of Gol Gohar, Sirjan. The title of the largest producer of iron ore in the country was calculated, and the social cost resulting from the emission of pollutants was also evaluated. Finally, in this study, solutions and mechanisms for reducing environmental costs have been proposed.
Considering that the ability to absorb pollutants by the environment is limited, the shadow price of pollutants, which represents their real social cost, should be taken into consideration. The damages should also be determined based on the shadow price of the pollutants. In other words, the amounts of pollutant emission should be calculated and while taking into account the allowed limit of pollutant emission and shadow prices, based on a legal plan, the environmental costs should be reimbursed. Taking such measures would surely require more studies and capable executive management system

Abstract
Chivalry and agility that is also translated as "generosity" have been very important phenomenon in the social history of Iran and surrounding countries and is a spiritual way of life that seems to have its roots in pre-Islamic Iran. They are divided into different categories that are called as ‘caliber’ and ‘brat’ in Persian and Arabic literature, respectively. Caliber was a group that had made ethics and campaign-specific career choice and self-indulgence and brat also defined as impoverished with no money, on the other hand people who had no interest in wealth and joined that house because of poverty and social imbalance. This study relying on comparative literature of American schools that merely doesn’t see the criteria existence of affect and affected attempt to make a comparative study of these two emerging fields within the common social and ethical implications. It seems that the main reason behind the formation of each of two groups was lack of community-based justice and social harmony. The most common social and moral characteristics of the two groups are: clemency; patience in the face of adversity, courage, generosity, support for the poor; combat skills including shooting, fighting, theft and robbery. This article also refers to common moral and social characteristics and examines the reasons behind the rise of the two groups.

Abstract
The citrus leafminer, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) is a major invasive pest of citrus in Tunisia. In order to help the implementation of an efficient integrated management strategy, it was essential to assess the genetic diversity and population structure of the pest. For this purpose, random-amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) was applied, using eight oligo-nucleotide primers, to reveal genetic variability among eight populations of P. citrella, originating from the north, center and south of Tunisia. A total of 66 RAPD markers and 33 phenotypes were generated. Inter-population polymorphism was revealed, using the percentage of polymorphic markers (62.12 %), mean number of phenotypes generated per primer (4.125) and mean genetic distance (0.199). Hierarchical analysis, using the UPGMA method, indicated that the genetic variability was influenced by the regional distribution. This pattern of population clustering was supported by Principal Coordinate Analysis (PCO). Yet, a weak correlation (0.69) was revealed between genetic and geographic distances, suggesting that climatic contrariety between the north and south of Tunisia plays a major role in the differentiation of P. citrella, leading to a restriction of gene flow between populations. Results obtained in this work show clear genetic differences, which should be considered in the development of control strategies.

Abstract
The aims of this study were to assess the effects of drought stress on peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) activities as well as free proline content and growth parameters of Pistacia khinjuk seedlings under drought stress. Therefore, the one-year seedlings of Pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhouse condition. Results showed that drought stress decreased height, collar diameter, shoot dry weight and root dry weight of P. khinjuk seedlings. But it had different effects onantioxidant enzyme activities in root and shoot of P. khinjuk seedlings. Drought stress increased CAT activity in shoot and root of seedlings and its activity was higher in 25% field capacity (FC) than other treatments. Also, the POD enzyme activity increased in root and shoot of seedlings subjected to drought stress. The SOD activity was at the lowest level in 100% FC than other treatments. The results also showed that free proline accumulation was lower in well watered seedlings and increased under drought stress.

Abstract
City is like a living entity, which regenerates constantly by constructing new buildings. With few exceptions, the character of cities have changed over time with the architectural styles fashionable in each period as well as the changing demands for their functionality. Most often, the character is a combination of styles and it is important that this evolution is maintained and the vitality of places can be extended. In fact, city is the result of different historical periods and includes historical loads of various periods; and, contemporary eras are in this process, too. Our constructions will form some parts of the city in future and will cause a layer in this inherited complex, and will make specification and identity of cities and will be an inheritance for posterity. Although preservation is considered as a major step in revitalization of historic sites and buildings, ironically these sites benefit from being extended. In fact opposing construction of new structures on these sites could mean taking away the liveliness of the city and the long term standing of these sites as a historical place. In contrary, expansion and construction of new buildings on these sites maintains the history of the site to the new era and enrich its history. New architectural styles and materials are often introduced into the city initially on the periphery and then in empty plots or as replacements for dilapidated buildings. Sometimes, existing buildings are adapted to the new styles. New architecture in an existing setting will set out to copy, mimic, integrate, harmonize with, contrast, juxtapose on or even compete with the existing context. Each situation may necessitate a different approach. However, construction of these new structures on a historic context is a very delicate task which requires well-planned regulations as these new structures link the contemporary architecture to the values and characteristics of the site. Over the past few centuries a great afford has been carried out, thorough the world and particularity within the central Europe, for design of such regulations and legislations for revitalization and conservation of these sites. This has left a legacy of resolutions, recommendations and charters in this field around the world that are result of experience gained from a variety of approaches in this field in different countries. In order to achieve a design guideline for new constructions in historic context, the purpose of this paper is review of ideas and theories, agreements and charters associated with the presence of new constructions in historic context. In this paper, we will review the theory of theorists that had more impact on the approaches. We will then look at the details of the agreements between the international bodies that directly or indirectly influenced these regulations and had key roles in their design. At the end, we will set a table which will be based on the approach of any of the agreements, and the evolution of this approach is discussed in international scale.

Abstract
The function of traditional characters in the modern poetry Arabic and Persian has different aspects, which using the mask of characters is one of the most important of them. Nowadays, the poets use the mask as an eloquent and artistic technic to explain about their ideas. Sometimes, they apply the mask of a religious character to confabulate with the audiences by it. Shamlu and Adonis used “religious mask” in their poetic works to visualize their thought. Thus the fundamental function of religious characters can be seen in their works because they wanted to benefit the actual and potential capacity of characters. This research is based on the analysis-narration criticism, and will study the fundamental usage of religious mask in the poets of Shamlu and Adonis based on narrative structure and images of their works. For this purpose, firstly, we studied the concept and meaning of religious mask and the reasons of its function in modern poetry; then we looked for the fundamental function of religious mask in the poets of Shamlu and Adonis to gain similar and different aspects of their application.

Abstract
Background: Campylobacter spp. are the common pathogens that infect human beings via food. These bacteria are vibrio and have been implicated in abortion. Serotyping is the best way for typing with Penner scheme. C. jejuni and C. coli have 65 serotypes. C. coli is common in birds and dogs. Due to high rate of prevalence of Campylobacter in red-meat, chicken-meat and egg-shell, a suitable method to detect their prevalence, the most common species and serotyping group was necessary. This article describes the prevalence of Campylobacter infection, common serotyping group in 330 samples of red- meat, hen-meat and egg-shell. Materials and Methods: With three methods: enrichment, selective Preston and Skirrow and filtration with membrane filters Campylobacter swere incubated. Bacterial species were identified with physiological and biochemical tests. Penner serotyping was defined with reference antiserum Ag-O and direct agglutination. Results: Prevalence of Campylobacter infection was 21(23%) in red meat, 33(27.5%) in hen meat and 38(31.6%) in eggshell. In egg-shell samples: C. jejuni 20, C. coli 14, C. lari 3 and C. concisus 1 case. In meat common Penner serotyping for C. jejuni O2 had the highest rate. In hen, common Penner serotyping: for C. jejuni O3 and in egg-shell for O1, O2 and O3 had the highest rate. Conclusion: Most infection of campylobacter was found in egg-shell; most common species in these three samples were C. jejuni, then C. coli and C. lari. No C. consicus was found in meat but it was found in hen and egg-shells. In common Penner serotyping for C. jejuni O2 and O3 were the most common and for C. coli in meat O49 and in hen and eggshell O5 were the highest.

Abstract
Hippodamia variegata is an efficient and most abundant predatory coccinellids in many countries. Understanding the ability of long-term low temperature survival in beneficial insects can be used to make better predictions about subsequent abundance and hence the biological control potential in the next spring and summer. So in this study, effects of long-term temperatures were investigated on mortality and supercooling point (SCP) of field collected (pre-diapausing) and overwintering aggregations of H. variegata adults. Unlike the pre-diapausing insects, aggregated coccinellids could easily survive at -3 and 0 °C for one month. One month acclimation at 10 °C caused more than 80% mortality in overwintering adults, indicating the higher temperatures were not appropriate for overwintering aggregated coccinellid. In December and January, when diapause was in its highest level, changing the habitat temperature did not affect SCP. Acclimation at 5 and 0 °C for one month decreased SCP of pre-diapausing adults, collected from aphid infested plants in October. Our study revealed that exposure to temperatures below 0 °C happened usually in natural condition for a long term period, may be necessary for overwintering of the coccinellid.

Abstract
An important subject in the field of linguistics is the impact of one thought system on the community of lingual symbols. The relationship between mind and language conventions has long been of interest to linguists. The importance of this relationship becomes more prominent in comparative approaches where, through comparative study and analysis of the main schemas of the ideas of several thinkers or artists, the researcher traces the consistent and common use of linguistic symbols.
In the hermeneutic analysis of the works of Mowlana Jalal ad-Din Mohammad Rumi, the interpretation of symbols, analogy and codes governing his mind and language is a major research interest. One of the most important branches among these researches concerns the kinship of Mowlana’s language codes with other thinkers and artists.
On the other hand, Nietzsche, as a transcendental thinker, tries to use a symbolic language in explaining his thinking system. Due to his familiarity with the culture and literature of the East and the essential sameness of some of his principles with Mowlana’s transcendental approaches about the existence, morality, art , etc., Nietzsche achieves a set of symbols common with Rumi, which forms a shared language between the two thinkers.

Abstract
Effect of controlled atmospheres (CAs) at various concentrations of CO2, N2 and O2 on the lethal times of Tribolium castaneum and Trogoderma granarium was investigated at 20 and 30 ºC. Experiments were performed using a recirculatory multi-flask apparatus. The results revealed that, the shortest times (0.1, 0.3 and 0.9 day for adults, larvae and pupae, respectively) required to obtain 50% mortality of T. castaneum stages were at 100% CO2 followed by 75% CO2, 50% CO2, 99% N2 + 1% O2 and 25% CO2, at higher tested temperature (30 °C). Adults were more sensitive to the different treated CAs than larvae, while pupae were the most tolerant stages. Diapausing larvae of T. granarium were the most tolerant to all treated CAs at tested temperatures. The effectiveness of CAs to decrease its LT50 values were 100% CO2 followed by 99% N2 + 1% O2 and 98% N2 + 2% O2 at 30°C. It may be concluded that diapausing larvae are more difficult to control with CAs than normal larvae. A treatment with N2 relying on the absence of O2 will take a longer treatment time to control the diapausing larvae and in late winter, exposure times needed for control may be even longer. If CAs were to be applied under such circumstances, a high content of CO2 would be the best option to achieve control in a comparatively short time.

Abstract
Oxygen concentration the environment and cellular organisms is one of the effective factors during normal development of organisms. In the present study, the transcription levels of the hypoxia-inducible factors (hif-1, hif-2) were evaluated during development of an ancient fish species Acipenser persicus, in the normal oxygen density of environment. The transcription of hif-1, hif-2 detected in all developmental time-points defined, from embryo to juvenile stages. Target genes transcriptions were normalized using RPL6 as reference gene. Changes in normalized hif-1, hif-2 mRNA expression were statistically significant throughout developmental points (p<0.05). Our data revealed that the mRNA expression of hifs were low during embryonic development and then upregulated significantly at hatching and early larval time-points. Then, in the late larval development and juvenile stage the expression of hifs started to decline. The comparison between hif-1 and hif-2 mRNA transcription showed that maximum gene expressions of hif-1and hif-2 occurred in 15 and 20 days after hatching, respectively. The increased expression of hifs suggests their association with two important events in the larval evolution, viz. internal feeding (yolk absorption) and external feeding. Also, the observed increase in mRNA expression of hifs during larval development of A. persicus can be attributed to increase in oxygen demand.

Abstract
Conflagration of forests and rangelands is one of the most frequent events in Iran. It is regarded as one of the most important parts of land degradation that occurred due to range destruction and desertification. This study was conducted in Boroujerd, Lorestan Province in west of Iran in 2013 to determine the fire risk model. The data prepared for the study area involved the vegetation types, land use, elevation, slope, aspect, standard topographic map and mean annual climatic data (evaporation, rainfall and temperature). Landsat ETM+ data were used for the image analysis. Analytical Hierarchical Process (AHP) model was applied to weigh and generate the fire risk map. Results showed that the highest weight of factors has been given to the land use because land use contribute to the maximum extent due to inflammability factor. The second highest weight was related to rainfall since it caused the biomass growth (fuel factor). Land use and rain played important roles in the modeling of fire risk zonation. The third one was attributed to the evaporation because of fuel drying and highly inflammability. The other variables comparatively had less impact on fire risk. Based on the statistics achieved for different weight classes, the map was reclassified into five classes as very low, low, moderate, high and very high in order to generate fire risk area map. Also, final map showed that most of the fires which occurred in the last year (5 fire control points about 4812.323 ha) might be put in the firing class of very high risk. Finally, about 42353.36 ha of the total area fell in the class of very high fire risk. The results indicated that 90% of burned areas were located in high risk class.

Abstract
Suhrawardi’s hermeneutical approach to the elements, components and narratives of the Shahnameh, as they are expressed in his mystical treatises, delineates the metamorphosis of the epico-mythic Weltanschauung into a mystico-gnostic worldview. We will best understand this metamorphosis by contrasting the hermeneutical principles of Suhrawardi with those of Ferdowsi in interpreting various myths and epic narratives. Ferdowsi’s hermeneutics can be described as “logocentric,” a term which highlights the role of λόγος in imposing a rational interpretation on the seemingly illogical and counterfactual aspects of myth and epic narrative. In contrast, Suhrawardi’s hermeneutics is dominated by different ontological and epistemological principles that turn it into what can be designated as “radical hermeneutics,” a theory of reading whose radicality consists in making the Erlebnis of the reader and his or her intentiō lectoris the focal point of interpretation. The paper will scrutinize the way in which Suhrawardi interprets the epico-mythic elements of the Shahnameh as mystical symbols in the context of his Gnostic and illuminationist worldview and thus metamorphoses the epic into the mystical.
