Siyah Qalam
The album of Muḥammad Siyāh Qalam or Siāh-Qalam (lit. 'the Black Pen'; Persian: محمد سیاه قَلَم; Turkish: Mehmed Siyah Kalem), likely of Turkic origin, comprises around 80 extant late 14th and early 15th century folio paintings, ink drawings (qalam-siāhi), and calligraphies, on various material, sometimes silk. The album that contains these paintings, most of which are signed as Mehmet or Muhammad Siyah Qalam, is called the Fatih.
