Uranometria

It was published in Augsburg in 1603 by Christoph Mang (Christophorus Mangus)[1] under the full title Uranometria: omnium asterismorum continens schemata, nova methodo delineata, aereis laminis expressa (from Latin: Uranometria, containing charts of all the constellations, drawn by a new method and engraved on copper plates).

[2] The final two charts are planispheres labeled "Synopsis coeli superioris borea" and "Synopsis coeli inferioris austrina", or (roughly), "Overview of the northern celestial hemisphere" and "Overview of the southern celestial hemisphere".

Brahe's expanded list had circulated in manuscript since 1598 and was available in graphic form on the celestial globes of Petrus Plancius, Hondius, and Willem Blaeu.

Uranometria introduced the convention of labelling stars by Greek and Latin letters, known as Bayer designations, a system still in use today.

Bayer took the southern star positions and constellation names for the 49th plate from the catalog of Dutch navigator Pieter Dirkszoon Keyser, who corrected the older observations of Amerigo Vespucci and Andrea Corsali, as well as the report of Pedro de Medina.

[5] The engraved title page of Uranometria is signed in the shadows of the central scroll at the bottom with the monogram AMF, for "Alexander Mair fecit", and the date MDCIII.

"Ουδεις αγεωμέτρητος εισίτω" (Oudis ageométritos isíto) i.e. "Let no one ignorant of geometry enter" was supposedly inscribed at the entrance to Plato's Academy.
