 In addition to these works, translated within the circle of al-Kindi, two doxographies were translated into Arabic in this period: the Placita of the pseudo-Plutarch, accounting for Greek cosmologies from the Presocratics to the  Stoics,[48]  and the Refutation of all the Heresies by Hyppolitus of Rome; the latter was reworked in light of the theological discussions of the 9th century Baghdad and attributed to Ammonius, the Alexandrian commentator of  Aristotle.[49]
