Stephen of Pisa and Antioch: \textit{Liber mamonis}. An introduction to Ptolemaic cosmology and astronomy from the early Crusader states (Q2420015)

Based on the author's doctoral dissertation [The Latin reception of Arabic astronomy and cosmology in mid-twelfth-century Antioch: the \textit{Liber mamonis} and the Dresden \textit{Almagest}. London: University of London (Diss.) (2013)], this is the definitive edition of a work in Latin by Stephen of Pisa and Antioch (also known as Stephen the Philosopher), a 12th-century translator from Arabic and scholar, the \textit{Liber mamonis}, based on the only known manuscript, the MS Cambrai, Médiathèque d'Agglomération, A930. It contains not only the Latin text of the \textit{Liber mamonis} and its English translation, but also a detailed introduction to studies in Arabic astronomy in the early Crusader states, on the author and his main source, which was Ibn al-Haytham's \textit{On the configuration of the world}, itself a popular presentation of Ptolemaic cosmology, on the many changes Stephen of Antioch introduced in his ``translation'', which renders it significantly different from its unnamed original (it was only recently, in the 21st century, that scholars convincingly determined both the authorship of the \textit{Liber mamonis} and the fact that al-Haytham's \textit{On the configuration of the world} served as its source), the rationale for those changes and additions, as well as of his comments.
