Bogos Efendi Şaşiyan was an Ottoman Armenian painter. He was son of a prominent family of court physicians in Istanbul, studied law in Venice in an Armenian Catholic college and, back in Istanbul, started a bureaucratic career.
Şaşiyan had no formal education in painting, yet, along with Osman Hamdi Bey and Köçeoğlu Krikor, he was involved in founding the first Ottoman artistic society and in organizing art exhibitions. Şaşiyan took part in the publication on ottoman architecture published on occasion of the Vienna world’s fair (Die Ottomanische Baukunst / L’Architecture ottomane / Uṣūl-i Miʿmāriyye-i ʿUsmaniyye). His contributions are mainly monochrome renderings of architectural decoration (Ersoy, 2015, pp. 124–125.)
