De pulsibus, by Aegidius Corboliensis, 1481

Ff. 87-97 of MS 169 contain the treatise, De pulsibus, by the French royal physician, Gilles de Corbeil (known by the Latinisation of his name, 'Aegidius Corboliensis '). As well as a 12th-13th century royal physician, Gilles was dedicated to Academic medicine in France, and promoted the Salernitian school. As a teacher of medicine, he composed two poems for students, the De urinis and De pulsibus. Both became widely used, copied and commented upon as medieval medical didactic texts.

The De pulsibus didactic poem deals with the theory of pulses based on Galenic thought, in 380 verses. It begins in MS 169 on f. 87v with a prologue: Cum autem cor et epar-est ergo titulus talis. Incipit liber Magistri Egidii de pulsibus metrice conpositus his habitis ad litteras accedamus. Incipit prohemium. The poem itself begins with Ingenii vires modicis conatibus impar... The text ends on f. 97v with the final words: Jam sterilis cultum philareti vomeris horret. Expliciunt versus Magistri Egidii de pulsibus.
