Seltene erste Ausgabe von Christmanns Werk über sphärische Geometrie in Bezug auf die Beobachtung der Sonne, über Jahre durchgeführt mit einem selbst entwickelten Sextanten. - DSB IV, 221f. - Houzeau/L. 2883 - Poggendorff I, 443 - Zinner 3884. - Jacob Christmann (1554-1613) war "Professor der Logik in Heidelberg ... Er schrieb Arbeiten über die Bewegung von Sonne und Mond und hat als erster das Fernrohr in Verbindung mit Meßgeräten verwendet" (Zinner, Astronomische Instrumente 280). - "On the death of Valentin Otho, Christmann inherited the entire library of G. J. Rheticus, which had been in Otho's keeping. This collection contained trigonometric tables more extensive than those that Rheticus had published in the Opus Palatinum of 1596 ... as well as the original manuscript of Copernicus' 'De revolutionibus orbium coelestium'. The inclusion of instruments in the bequest stimulated Christmann to begin making astronomical observations. In 1604 he proposed to Kepler that they should exchange the results of their researches. Christman was the first to use the telescope in conjunction with such instruments as the sextant or Jacob's staff." (DSB). - Teils etwas gebräunt. Gutes Exemplar.
