Constellations: Triangulum Australe -- Another Carpenters' Tool
|Triangulum from Bayer's Uranometria
Bayer was born in Rain, Bavaria in 1572, began his study of philosophy in Ingolstadt in 1592, and moved later to Augsburg later to begin work as a lawyer. He soon grew interested in astronomy, and published Uranometria in 1603 as a popular work. It was the first atlas to make use of Tycho Brahe's accurate measurements of stellar positions. These were far better than Ptolemy's rather incomplete listing. In addition, Bayer added 12 southern constellations to Ptolemy's original 48.
Bayer became legal advisor to the Augsburg city council in 1612 and died in 1625. For more information on Uranometria, click here.
