English: I used some texts from a pdf on Academia: T.C. Selçuk Üniversitesi Edebiyat Fakültei: Ahi Şerafettin (Arslanhane) Camii by Serdar Laikgil. Sanat Tarihi Anabilim Dalı, Nisan-2015, Konya. Google-translated is states: (some edits by me) “The mosque contains the most unique tile mosaic example of the Anatolian era mihrabs […] as the first Anatolian example where tile mosaic work and plaster relief decoration were made together. The plaster reliefs reflect the characteristics of the Great Seljuk period plaster work in Iran in the 12th and early 13th centuries. Turquoise, eggplant purple and black colors typical of the Seljuk period were used in the tile mosaic decoration. Geometric and plant elements in the tile decorations were used by combining them. The muqarnas niche of the mihrab, the first and third borders of the niche edges from the inside to the outside, are decorated with tile mosaic. Star, triangle, square and circle shaped tile pieces were brought together in the cave to form repeated geometric compositions. The top crowning the mihrab is made of plaster. It is decorated with shapes resembling abstract dragon motifs with perforated bodies, like strainers, on a rumi ground. The abstract dragon shapes are notable in the plaster reliefs around the rumis and very realistic peony motifs. The plaster columns surrounding the mihrab niche are covered with openwork rumi patterns. Here too, on a rumi ground, there is a Neshi script at the bottom and a Kufic script at the top. The capitals of the columns are in a style called “Bell type” or “Vase type”.
