Bardaisan

"Bardesanes’s faith was true after his master Valentinus, the founder of Gnostic schools in Alexandria and Rome, and orthodox Christians have cursed him bitterly for it. Ephraim of Edessa, a father of the Church, writing 120 years after his death, says that he died “with the Lord in his mouth and demons in his heart”. He accused Bardesanes of being a heretic and sophist, a greedy sheep-dog in league with the wolves, and a cunning dissembler practicing deceit with his songs. If this is what a Christian saint has to say about his theology, it is something of an irony that Roman Catholic scholars are so eager to accept his geography."

"“Bardesanes was also a great student of Indian religion, and wrote a book on the subject, from which the Platonist Porphyry subsequently quoted. But it is as a poet and writer on Christian theology and theosophy that Bardesanes gained so wide a reputation; he wrote many books in Syriac and also Greek ... [and] he was the first to adapt the Syriac tongue to metrical forms and set the words to music; these hymns became immensely popular, not only in the Edessene kingdom but wherever the Syriac tongue was spoken.”"
