  According to a widely accepted hypothesis, Eustratios of Nicaea and Michael of Ephesus were two of the contributors to a series of commentaries, initiated by the princess and historian Anna Komnene, on previously neglected Aristotelian works. Their commentaries, in which they followed ancient models, some of which are now lost, but also added their own insightful remarks, were partly translated into Latin and played a role in the development of Western Aristotelianism in the 13th century.
