Abu'l-'Anbas Saymari Mohammad bin Eshaq bin Abi'l-'Anbas bin Al-Maghira bin Mahan (Persian: ابوالعنباس صیمری; Arabic: أبو العنبس محمّد بن إسحاق بن إبراهيم الصيمري) was an Iranian astrologer, astronomer, poet and author. He was born in 213/828 in Kufa, and died in 275/889. He seems to have spent much of his time at the caliphal court from Motawakkel's reign (847 – 861) to Moʿtamed's (870 – 892). His great-great-grandfather's name, and his knowledge of the Sasanian astrologers Zaradūšt and Bozorjmehr, indicates that he was of Iranian origin.
