Julius Schiller (c. 1580 – 1627) was a lawyer from Augsburg, who like his fellow citizen and colleague Johann Bayer published a star atlas in celestial cartography. In the year of his death, Schiller, with Bayer's assistance, published the star atlas which replaced the pagan names of constellations with biblical and early Christian figures. Specifically, Schiller replaced the zodiacal constellations with the twelve apostles, the northern constellations by figures from the New Testament and the southern constellations by figures from the Old Testament.
