Mihrab of Pir-i Bakran - Ilkhanid workshop - Iran, Pir Bakran - c 1298-1313

Near Isfahan, in the green valley of the Zayandeh River, the mausoleum of Pir-i Bakran holds one of the richest carved stucco walls in Iran. Built for the Sufi teacher Sheikh Muhammad ibn Bakran after his death in 1303, its mihrab was finished by 1312 in the Azari style of the Ilkhanid era.

A garden carved in wet plaster

The technique is gach-bori, gypsum cut fast in the sharp plaster called gach-e tiz and undercut so shadow pools behind every leaf. Iranian scholars call this very high relief seh-gacha. Two coats were laid down — a base for fine ornament, a second for the raised forms — a layering known as madar-o farzand, mother and child. One inscription still carries traces of gold.

The composition works as nested frames:

• a niche set inside an arch
• the arch set inside a rectangle
• the rectangle framed on three sides by broad bands of thuluth script

Every corner above the arch is packed with fruit, leaves and blossoms, so tightly there is no ground left — the Qur'an's paradise turned into a wall.

Layers of history and script

The iwan overhead descends from Parthian houses and Sasanian palaces. The plaster tradition reaches back to Achaemenid Persepolis and the painted stucco of Qal'a-ye Yazdegerd. Inside the flowing vegetation, tiny panels of square Kufic hide like mazes, and a pilaster carries the names of the four Rightly Guided Caliphs — a trace of the years when Iran's Mongol rulers still followed Sunni Islam.

The hall's inscription band is signed by Mohammad Shah Naqqash. The lustre tiles and deep blue lajvardina that once glittered around it were stripped early and scattered to museums abroad. What remains — brick, plaster, and one master's name — still stands beneath scaffolding today.
