De revolutionibus orbium coelestium libri VI. Second edition

The second edition of "De revolutionibus orbium coelestium" was published in 1566 in Basel, 23 years after the first edition, the so-called Nuremberg edition. The book was published by Henryk Petri's publishing house - the same one in which George Joachim Rheticus published "Narratio prima" in 1540. Rheticus' work contained an initial description of the discovery of the Toruń astronomer and played a key role in popularizing the heliocentric theory. The publishing house of Adam Petri (1454-1527) and his son Henryk Petri (1508-1579) was one of the most active in 16th-century Basel. After his father's death in 1530, Henryk took over his workshop and continued printing scientific works, mainly in the field of medicine and astronomy.
