Bardaisan

← Encyclopedia

Bardaisan — Bardesanes in the Greek sources — was a Christian thinker, poet, and astrologer of Edessa, the Syriac-speaking city on the eastern edge of the Roman world, active from the late second century until his death in 222. He stands near the head of Syriac Christian literature: among the first to write theology and philosophy in Syriac, and to set Christian teaching to music. For centuries his name carried the charge of heresy. What he actually held is harder to recover than the charge.

The bare facts are reasonably firm. He was born in 154, moved in the circle of the Edessene court under Abgar VIII, and was learned in Greek philosophy and in the astral science of the older Mesopotamian world. The one work that gives a direct view of his thought is the Book of the Laws of Countries, a dialogue preserved in Syriac and composed not by Bardaisan himself but by a pupil who set down his master’s teaching — so that even the clearest source comes at one remove.

Its theme is the oldest problem the stars pose: if the heavens govern human life, what becomes of choice and of right and wrong? The dialogue grants the planets real power over the body and over the accidents of fortune, yet argues that custom and law differ from people to people in ways no horoscope can explain — whole nations behave by their own ordinances against what their stars would dictate. From this it concludes that nature, fate, and free will each rule their own province: the stars bind the outer life, but the will, given by God, is not theirs to command. The argument is a careful middle path between surrender to astrology and its outright denial.

How far Bardaisan strayed from later orthodoxy is genuinely contested. The heresiologists who shaped his reputation accused him of a dualist cosmology, of teaching pre-existent elements alongside God, and of denying the bodily resurrection; they grouped him with the Valentinians and the wider gnostic currents of the age. Modern scholarship reads the surviving evidence more cautiously. The dialogue that survives is closer to a philosophical theism than to any developed gnostic myth, and much of what was reported as his may belong to followers who carried his ideas further than he did. The picture that emerges is of a learned Christian working at the meeting point of Greek philosophy, Mesopotamian astrology, and the new faith, whose synthesis was too independent for the church that came after him.

His hymns were the more lasting scandal and the more lasting influence. He and his son Harmonius are said to have composed psalms — by tradition a hundred and fifty — that spread his teaching through song, and they were popular enough that Ephrem the Syrian, a century later, wrote orthodox hymns in the same metres to displace them. Almost none of Bardaisan’s own verse survives. What endured was the form: in answering him, the Syriac church took up the sung hymn as a vehicle of doctrine, and kept it.
