Opera omnia, edidit I.L.E. Dreyer
A Latin scholarly edition of Tycho Brahe's complete astronomical writings, edited by J. L. E. Dreyer and issued in Copenhagen by Gyldendal in 1913 for astronomers and historians of science. The plates reproduce Tycho's own observational material: hatched circles marking shaded portions of eclipsed disks, numbered sketches of lunar and planetary appearances, hand-lettered star-position diagrams with Latin names along a horizon line, and a woodcut zodiac wheel enclosing a hexagram and star.
