The decans of Albumasar: The images of stars rising with the 36 faces

This is a book about fixed stars and how a few pages from an astrological book deeply influenced Western history. This book, the Great Introduction, written by Abu Ma'shar al-Balkhi (known as Albumasar) influenced art, history, religion. The history of this book and how some images from an Hellenistic author travelled from Greece to India and Iran and then came back to Europe is the history of astrology.
