Tychonis Brake Opera Omnia

Abstract

THE first volume of this sumptuous reprint of the complete works of Tycho Brahe was noticed in NATURE last April. There will be thirteen volumes in all, of which the second has now appeared, containing the first and second of the three parts of the Progymnasmata. This is a posthumous work, as although a large portion of it was printed at Hveen under Tycho's direction, it was not completed until 1602, the year after his death; Kepler saw it through the press, and added an appendix. It is a general treatise on astronomy, both observational and theoretical; it commences with a dedication to the Emperor Rudolph II., and the diploma that he granted to Tycho. A document follows that is of special interest to British readers; it is the “ privilege” of copyright in Scotland for thirty years, granted to Tycho by James VI. on the occasion of his visit to Hveen in 1590, just after his marriage to Anne of Denmark. Two Latin epigrams that were sent to Tycho by James are also printed.
