The three inscriptions read: Dar ruz-e shanzdahom-e shahr-e rajab al-morajjab sana 1097 be-jehat-e moraqqa' be-etmam rasid (It was finished for the album on the sixteen of Rajab, 1097 (29 June 1684)'; mashshaqahu mo'in mosavver ghafara 'anhu zunubihi (It was drawn by Mu'in Musavvir, may [God] forgive his sins, the last word with a slight spelling error'; and huwa. be-jehat-e farzandi a'izzi khwaja ghiyath al-din 'ali mobarak bad (He (God). For my dear son Ghiyath al-Din 'Ali May it be blessed).
A comparable study of a bird signed by Mu'in's master, Reza Abbasi, sold in these Rooms in November 28th 1983, lot 125. The bird perches on a rock against a background very similar to this example. There is a group of bird drawings similar to these executed by Reza and his students, Mu'in and Sheikh 'Abbasi, all of which vary in date to around 1700.
Mu'in is however more commonly known for his studies of single, usually male figures as well as his manuscript illumination and illustration.
