Shams al-Dīn al-Bukhārī is cited in various Greek versions of Arabic and Persian zījes in the last decade of the 13th century in Marāgha and Tabrīz. He was instrumental for the Byzantine scholar Gregory Chioniades.  The last mention of Bukhārī in the Byzantine sources is in the Tribiblos (ca 1350) by Theodore Meliteniotes. [BEA Mercier]
