Work B.1.2a

Dixerunt Ptolemeus et Hermes quod locus Lune in hora...

Text ‘(Paris, BnF, lat. 7307, f. 1r) Dixerunt Ptholomeus et Hermes quod locus Lune in hora que infunditur sperma est gradus ascendentis nativitatis, et in loco qui erat gradus ascendentis in hora infusionis spermatis erit Luna in nativitate — et cum eo remanserit equa Lunam et ubi inveneris erit ascendens nativitatis. Dixit magister Abraamis Bendeur: Gradus infusionis spermatis non erit ex toto Lune locus in nativitate vel ipse erit oppositus. Et similiter erit de ascendente nati, id est non erit locus Lune in spermatis infusione vel ipse erit aut ei oppositus ex hoc expertus fuit multotiens.’

Content A brief text on the rectification of nativities based on the idea that the position of the ascendant at the time of birth is identical with the position of the Moon at the time of conception, i.e. the so-called ‘Trutina Hermetis’.

Origin This chapter is one of the two additional chapters generally found together with the Centiloquium in Plato of Tivoli’s and the ‘Mundanorum’ versions (see B.1.2 and B.1.4 above), either at the beginning or at the end. It is related to v. 51 of the Centiloquium, which deals with the same topic, but its origin and exact relationship to the Centiloquium remain to be investigated. The identity of ‘Abraam Bendeur’ (or ‘Isbendeut’) is unclear.
