About the cover image

The portrait of Tycho Brahe on the front cover is reproduced from the Library’s copy of Isaac Bullart’s Academie des Sciences et des Artes (1682), volume 2, which in turn is an adaptation from the title-page portrait of Tycho’s Astronomiae Instauratae Mechanica (1602). Notice, on the left side of the arch, two Danish names which fit characters in Shakespeare’s Hamlet—Rosincrance and Guildensterne.
