The Madrasa Jaqmaqiye, built 1418-1420 by the Mamluk governor of Damascus, Jaqmaq al-Argunsawi (who later went on to become sultan in Cairo, 1438-52). The Ross Burns guidebook The monuments of Syria describes the façade as beautiful for its polychrome work of the period , but the inside with marble and pearl shell mosaics “striking, but the wood and marble sculpture are mediocre.” And indeed the Museum of Epigraphy housed here has “a collection of Arabic inscriptions including some early examples of Kufic lettering. “ I only took a picture of a tughra (Ottoman Turkish: طغراء; Ṭuğrā) is a calligraphic seal or signature of an Ottoman sultan that was affixed to all official documents and correspondence. It was also carved on his seal and stamped on the coins minted during his reign. (Wikipedia). I have some examples in my Turkey galleries, like here and next.
