Venerable Isaac the Syrian (of Nineveh)

Venerable Isaac the Syrian (of Nineveh) was born in the 7th century in Beth Qatraye (Qatar), Persia. Together with his brother he entered the monastery of Mar Matthew near Nineveh and was tonsured a monk. Drawn to solitary contemplation, he withdrew into the desert. Around 676 he was consecrated Bishop of Nineveh, but finding himself unable to reconcile ascetic solitude with pastoral administration, he resigned after only five months and retreated to a hermitage on Mount Matout, later to the monastery of Rabban Shabur in Khuzistan, where he spent the rest of his life in prayer, fasting, and writing. He went blind from excessive reading and weeping but continued dictating to disciples. He left a profound ascetic legacy — the famous "Ascetical Homilies," marked by deep spiritual experience and mystical theology, beloved reading among monks and laypeople alike. Veneration of St. Isaac spread widely in Russia from the late 14th–early 16th centuries through translations of his works. In the Russian Church his feast is kept jointly with St. Ephrem the Syrian.
