Albumasar's "Introduction" (Kitāb al‐mudkhal al‐kabīr, written c. 848) was first translated into Latin by John of Seville in 1133, as Introductorium in Astronomiam, and again, less literally and abridged, as De magnis coniunctionibus, by Herman of Carinthia in 1140.

Lemay (1962) argued that the writings of Albumasar were very likely the single most important original source for the recovery of Aristotle for medieval European scholars prior to the middle of the 12th century.

Herman of Carinthia's translation, De magnis coniunctionibus, was first printed by Erhard Ratdolt of Augsburg in 1488/9.

It was again printed in Venice, in 1506 and 1515.
