[141] The two standard lives of Tycho Brahe are the Vita Tychonis Brahei by Gassendi (1655) till recently the sole source of information, and Dreyer's Tycho Brahe (1890) based not only on Gassendi but on the documentary evidence disclosed by the researches of the 19th century. For Tycho's works I have used the Opera Omnia published at Frankfort in 1648. The Danish Royal Scientific Society has issued a reprint (1901) of the rare 1573 edition of the De Nova Stella.
