Uncommon third edition with numerous marginal annotations to the first part, of Guido Grandi’s important study of conic sections, first published in 1722.

Grandi (1671 – 1742) was a monk in the Camaldolese order, and was one of the first writers in Italy to popularise the new science of Leibniz and Newton. He became court mathematician to Cosimo III de Medici in 1707, and was elected a Fellow of the Royal Society on a visit to England two years later. He became professor of mathematics at the University of Pisa in 1714, a chair he held until his death. He was the first Italian to teach infinitesimal calculus, and worked extensively in the fields of geometry and hydraulics.

We have found no information about Gregorio Fabrizi, the owner and presumed annotator (a churchman of the same name, also from Terni, is known of, but was only born in 1770). The annotations elaborate on, and occasionally correct, sections over the first 40 pages, and are in both Latin and Italian.

Riccardi, I-624; OCLC records three copies outside Italy, at Oklahoma, Stanford, and the Delft University of Technology.

‘Prieres et ceremonies de l’ordination 1766’.

An attractive manuscript ordinal detailing the ceremonies to be followed and the prayers to be employed in ordinations, covering the tonsure, admission to the minor orders of porter, lector, exorcist, and acolyte, and admission to the major orders of subdeacon, deacon, and priest.

Reference to Henri-Joseph-Claude de Bourdeilles (1720-1802), Bishop of Soissons from 1764 to 1790, indicates that our manuscript was employed in the diocese of Soissons, in the north of France.

On the tonsure the text states: ‘On prepare des ciseaux pour couper les cheveux et un bassin pour les mettre’. Lectors are instructed by the bishop: ‘Appliquez vous donc à prononcer la parole de Dieu, c’est à dire les lectures saintes, d’une maniere distincte et intelligible, et sans aucune alteration ou falsification , afin que les fidéles en soient instruits et édifiés.’ And exorcists are told: ‘vous recevez donc le pouvoir d’imposer les mains sur les possedés et par l’imposition de vos mains, par la grace du St Esprit, et par les paroles des exorcismes les esprits impurs sont forcés de sortir des corps qu’ils possedoient.’

Die Axiome der Wahrscheinlichkeitsrechnung.

Rare first edition of this doctoral dissertation on the solution of Hilbert’s sixth problem, written under the supervision of David Hilbert. The problem posed tried to axiomatize those branches of science in which mathematics is prevalent. Broggi here aims to establish a system with which to prove the consistency, completeness and the mutual independence of the axioms, following the model of Hilbert’s geometry.
