Work B.4

De cometis

Text ‘(ed. Boudet) Dixit Ptholomeus quod stelle cum caudis sunt 9, quarum prima est veru, secunda Tenaculum, tercia Pertica — significabit mortalitatem multam et decollatione’ [or: ‘... ipsa signaficabit in regibus et divitibus apparebit’]

Content A brief description of nine types of comets, together with their influence on earthly events.

Origin This chapter is one of the two additional chapters (with B.10) generally found together with the Centiloquium in Plato of Tivoli’s translation (B.1.2) and in the ‘Mundanorum’ version (B.1.4), either at the beginning or at the end. It is related to v. 99-100 of the Centiloquium, which deal with comets, but its origin and exact relationship to the Centiloquium remain to be investigated. The text exists in three versions: (1) the standard version (‘Dixit Ptholomeus quod stelle cum caudis sunt 9…’), generally found together with the Centiloquium in Plato of Tivoli’s translation; (2) an expanded version of the former (‘Ptholomeus in hoc libro tricas et tricarum nomina posuit…’), generally found together with the Centiloquium in the ‘Mundanorum’ version; (3) a version attributed to Robert Grosseteste and consisting of the expanded version followed by Grosseteste’s last part of his own De cometis (ed. Panti, 326-328, lines 112-145). The latter version occurs in MSS Erfurt, UFB, Amplon. Q. 361; Florence, BM, C 163 (among Grosseteste’s works); and Munich, BSB, Clm 588.
