Biographical/​Historical note:
Willem Janszoon Blaeu was a Dutch cartographer, atlas maker and publisher. He was born in 1571 and died in 1638.
Summary note:
Astronomical treatise, on the celestial and terrestrial globes, and on sundials. This manuscript largely corresponds to the first part of Willem Blaeu's "Institutio astronomica de usu globorum et sphaerarum caelestium ac terrestrium." Text begins: "Cap. 1. Quid et quotuplex sit globus". [Amsterdam] [mid-17th cent.] MS, 8vo., fols. [125]. Text on fols. [6r]-[86r], and [94r]-[105v]. Diagrams to fols. [30v] and [84r], a horoscope to [86r], tables to fols. [81r], [82r], [84v] and [85v]. Many headings, blank spaces for diagrams in second part. From mid seventeenth-century Holland. Displays the interest in instruments characteristic of the period of the Scientific Revolution. The first section covers the use of terrestrial and celestial globes, and the second section covers sundials. The work bears the influence of the 'Tractatus de globis,' by the English mathematician and explorer Robert Hues (1553-1632). Other sources include (cf. fol. [80v]) a set of ephemerides from Amsterdam, 1634 (the latest date mentioned in the book), the Frankfurt ephemerides of David Origanus (last published 1633), and the star tables of Tycho Brahe. The place on the terrestrial globe most frequently referred to is Amsterdam. On fol. [86]r is a horoscope for a certain 'D.A.M.' born on 9 October 1571. Six blank pages are left between a problem that is marked L (i.e. 50) and another marked LIV (54). There are also clarifying notes added to margins in a couple of spaces.
Binding note:
Contemporary vellum boards, title to spine, edges mottled red.
