First edition (issue A), edited by Egidio Bonsi and dedicated by the latter to Girolamo Seripando, general of the Order of St. Augustine, of Aegidius Romanus' commentary on the De causis libellus, a medieval philosophical treatise controversially attributed to the Islamic philosopher Alpharabius (Abu Nasr Muhammad al-Farabi, c. 870-950) and first translated into Latin by Gherardo da Cremona (1114-1187) (cf. A. Pattin, Le Liber de causis. Édition établie à l'aide de 90 manuscrits avec introduction et notes, in: “Tijdschrift voor Filosofie”, 28ste Jaarg., no. 1, March 1966, pp. 90-203).

Giles of Rome is one of the greatest philosophers and most prolific writers of the Middle Ages. He was born in Rome but became an Augustinian hermit in Paris, taught at the University of Paris, and was made archbishop of Bourges in 1295. Next to his philosophical writings, he is best known for his treatise De regimine principum (‘On the government of princes'), which he wrote for his pupil, the later king Philip the Fair (cf. F. Del Punta, G. Fioravanti & C. Luna, eds., Aegidii Romani Opera omnia, Florence, from 1987 onward).

Alpharabius is considered as the father of Islamic Neoplatonism and political philosophy. He is credited with presenting philosophy for the first time in the Islamic World as a coherent system, and was also an imoportant music theorist.
