[Illustration] FOOTNOTES: [1] An exhaustive study of the life and work of Willem Janszoon Blaeu does not exist. One of great value and interest is that by Baudet, P. J. H. _Leven en werken van Willem Jansz. Blaeu, uitgegeven door het Provincial Utrechtsch genootschap van kunsten en wetenschappen. Utrecht, 1871._ The author acknowledges here his indebtedness to Baudet’s work for invaluable aid in the preparation of this brief biography. [2] See illustration, p. 12. This, it will be noted, is a map signed “Insula Hvaena sive Venusia à Gviljelmo Blaev cum sum Tychone Astronomiae operam daret delineata.” [3] See illustration, p. 30. August 8, 1576, the corner-stone of the Castle of Uranienburg was laid with much ceremony, and the completion of the building was made possible through the generous contributions and patronage of Frederick II of Denmark. See, for a brief description, Wolf: _Geschichte der Astronomie, München, 1877, p. 277_; Picard, J. _Voyage d’Uranibourg, ou observations astronomiques faites en Dannemarck. (Mem. de l’Acad. royale des sciences depuis 1666 jusque à 1699, tom. VII, p. 197)_; Blaeu: _Atlas Major, vol. I, pp. 61-101_. Twelve illustrations of the Island of Hveen, and of the observatory of Uranienburg, with brief description, may here be found. These illustrations, it appears, were taken from Brahe: _Astronomiae instauratae mechanica. 1598._
