Harley MS 5425, ff 94r-140v

The Latin version of a medical compendium written by the Greek physician and philosopher Galen (c. 130-200) with its commentary by Alī ibn Ridwān (d. 1061, 1068 or 1089), generally known as Commentum Haly. Galen's text follows the Latin version probably made in Southern Italy in the mid-12th century, possibly directly from the original Greek text, and often identified in the manuscript tradition as the Translatio antiqua: see Richard J. Durling, 'Lectiones Galenicae: Techne iatrike (Kühn, I, 305-412)', Classical Philology, 63 (1968), pp. 56-57; Per Gunnar Ottosson, Scholastic Medicine and Philosophy (Naples: Bibliopolis, 1984), pp. 24-25.

Haly's commentary was possibly translated from Arabic into Latin also in the 12th century by Gerard of Cremona (c. 1114-1187) or by another member of the school of Toledo.
