Jeremiah Horrocks: 'Venus in sole visa'

The author's own manuscript, 206 folios. (f.3) 'Venus in sole visa: seu tractatus astronomicus de nobilissima Solis et Veneris coniunctione, Novembris die 24, 1639'. Chapter 4 and the last paragraph of chapter 9 are in different hands, and were probably added later. (f.40) 'Venus in sole visa...', the same treatise, in a slightly variant seventeen-chapter version, probably in the same hand. (f.84) 'Jeremiae Horroxj praeludium astronomicum liber primus, De motu solis', an unfinished tract. (f.87v) 'Astronomiae Lansbergianae censura'. (f.110) 'Jeremiae Horroxij Astronomiae Lansbergianae censura&cum Kepleriana comparatio'. (f.135) The rest of the manuscript is substantially blank, but with some headings, English notes on eclipses and geometrical problems, and diagrams.
