Alvaro de Oviedo
Expositiones in Quadripartitum
‘(Madrid, BN, 10063) ‘Expositiones in quartum Quadripartiti et sunt sententie H<aly>. Res igitur in quibus ea que ante partum: d<e> h<oc> quod ea que ante partum sunt sunt — (22ra) quia vapores iam incipiunt annullari et desiccari primum. Explicit. Domino Ihesu Christo gratie infinite. Amen, amen, amen. (22rb) [additional chapter] Hunc eundem modum docet H<aly> super tractatum Quadripartitum. Dixit Haly: Scias quod hec equatio accipitur per 4 annos — prime Quadripartiti.’
A commentary on the Quadripartitum, Books IV, III, I and II (in this order), with an additional chapter consisting of a commentary on Pseudo-Ptolemy’s Liber proiectionis radiorum stellarum (B.17).
Autograph of Alvaro de Oviedo, occurring in a MS mainly copied in his hand and whose content can be dated to the last two decades of the 13th century. ‘Haly’ most probably stands for Haly Abenrudian (see A.2.5), even though the source-text is unclear. Alvaro also knew (and glossed) the Quadripartitum both in Plato of Tivoli’s translation (A.2.1) and in the anonymous translation prior to c. 1250 (A.2.4), two texts preserved in a MS that belonged to him, Madrid, BN, 10053 (see).
