The Jāmeh Mosque of Ashtarjan (Persian: مسجد جامع اشترجان; Arabic: مسجد أشترجان), also known as the Jameh Mosque of Imanshahr and the Jameh Mosque of Oshtorjan, is a Shi'ite Friday mosque (jāmeh), located in Ashtarjan, Falavarjan County, in the province of Isfahan, Iran, situated approximately 36 kilometres (22 mi) south-west of the city of Esfahan. The mosque was added to the Iran National Heritage List on 3 March 1937, administered by the Cultural Heritage, Handicrafts and Tourism Organization of Iran.
History
Commissioned by an Ilkhanid administrator from Ashtarjan and dated by two separate inscriptions to 1315–16, this mosque has survived in excellent condition. Construction appears to have been swift, executed in phases over a brief period. The calligraphy inside the mosque mentions Ahmad ebn Banna and Haji Mohammad Kashi Tarash as the builders in charge of construction of the mosque. One of the main reasons for this mosque's survival after more than seven centuries is the metal wires that are placed inside the walls of the mosque that hold it together.
Patronage and political context The inscriptions reveal the complex political landscape of the Ilkhanid period. While the mosque was built under Oljeitu's officially Shi'ite rule (evidenced by the inclusion of the Twelve Imams' names), its construction was commissioned by Fakhr al-Dunya wa'l-Din Muhammad b. Mahmud b. 'Ali al-Ushturjani, identified as a mustawfi (state accountant) and munshi (secretary), rather than a high-ranking vizier. His inflated titles, like "King of the Viziers in the Universe," highlight the changing nature of political authority during this period.
Architecture
Exterior The north entrance of the mosque has a stalactite-vaulted recess framing the pointed arch portal. It has geometric decorations of light- and dark-blue tile mosaic combined with unglazed terracotta, and a foundation inscription in tile mosaic thuluth. There are also square Kufic panels made of terracotta and glazed tile. The two minarets flanking the portal are adorned with diagonal bands of banna’i script in glazed tiles. The east portal has a much simpler design than the north portal. It has stucco panels with an inscription with a floriated scroll ground.
Interior The interior of the mosque has an open court surrounded by prayer halls on three sides. The walls are decorated with a combination of plain mud brick and decorative plaster, featuring incised patterns. The dome chamber has squinches that transition into a 16-sided drum. Rectangular windows punctuate the dome. There are some decorative elements, such as terracotta ribs and painted plaster, that enhance the visual appeal, as well as vibrant polychrome painting in white, red, blue, and green. The mihrab is flanked by pointed arch recesses with intricate plaster strapwork. The prayer halls, located on three sides of the court, have been recently repaired. Plaster is extensively used for false bonding patterns, floral motifs, and vivid polychrome painting, while terracotta and glazed tiles enhance the interior with strapwork, geometric patterns, and inscriptions. Inscription bands in naskh and Kufic scripts are often rendered in contrasting colors such as blue and white. The mosque's interior may reflects the skill of its artisans, including “Ahmad ibn Muhammad” (builder) and “Hajji Muhammad” (tile-cutter), highlighting a legacy of exceptional Iranian craftsmanship. Their names are on the north outside portal, although the tile cutter refers only to tilework, of which there is almost none inside.
Specifications The mosque has an area of 1,500 square metres (16,000 sq ft), and has two northern and southern gates. The northern gate is 13 meters tall and surrounded by remnants of two brick minarets that are decorated with turquoise tiles. Only one third of these minarets survive; they were constructed in such a way that swinging one minaret would cause the swinging of the other minaret. The southern gate of the mosque is 7 metres (23 ft) tall and decorated with colorful plasterwork. The decoration is of greater importance than the primary structure. The diversity of patterns, materials, and combination of materials employed in the decoration represent a compendium of decorative techniques from around the country. Exposed brick is found only in the arcades, although possibly this area originally had a plaster coat as is employed extensively in the rest of the structure. The plaster is carved in a variety of decorative designs, including geometric patterns; floral motifs in high relief; simulated brick bond, and brick end-plugs – in some areas arranged to configure rectangular kufic inscriptions. On the sanctuary walls and dome, traces indicate that plaster was painted in a vivid array of colors. The lofty stucco mihrab describes an uncommon proportion, reaching the zone of transition. Across the interior of the dome, decorative terracotta elements form eight radial ribs; diverse painted plaster patterns fill the interstices. The northern entrance portal is lavishly decorated with mosaic faience, glazed and unglazed terracotta.
Minarets The minarets have been reduced to one-third of their original height over time. Despite this, the surviving sections continue to frame a 13-metre-high (43 ft) doorway, exemplifying the architectural sophistication of the Ilkhanid style.
Inscriptions The Ashtarjān mosque features an unexpectedly large number of inscriptions for its size and location. Miles identifies 47 distinct inscriptions or epigraphic compositions, including six building inscriptions that provide key details about the mosque's construction and its patron, twenty-seven Quranic passages chosen for their religious significance and decorative qualities, thirteen pious phrases, benedictions, or pious ejaculations that express common Islamic beliefs and invocations, and two visitors' inscriptions, one dating from 1333 and a later inscription from 1476 that documents a major renovation of the mosque. This abundance of inscriptions allows for a multifaceted understanding of the mosque and its history.
