when again Sirius is mentioned as rising together with the Ascendant at 19 Cancer.
Hi Margherita,
Interesting. Although the addition of zodiacal placement sounds a much later tradition no? The
Bundahishn is a fascinating text but seems to have interpolations at various historical points. For example, some seem to date after the Islamic conquest of Persia.
Its true Sirius is one of the royal stars of the ancient Persians! Probably the most important of them all to the ancient Persians. There is an Avestan (Zorasteran) hymn to Sirius. The Italian scholar Antonio Panaino has written on this topic extensively. The ancient Persians called Sirius "Tistrya''. Most writers on fixed stars list Regulus, Antares, Aldebaran and Fomalhaut as the 'Four Persian Royal Stars'. This is an error.
The source for this idea is not the ancient Persians but classical astrologers such as Firmicus (4th century CE) who mentions the four 'royal' stars mentioned as Regulus, Antares, Aldebaran and Fomalhaut. However, linking the classical idea of these stars on the ecliptic with the ancient Persian stars is mistaken.
Sirius was almost certainly one of the Persian Royal stars. Unfortunately, this misunderstanding is repeated over and over again by astrological writers on fixed stars in modern astrology. Its a trap lots of astrologers have fallen into. For example, Bernadette Brady gets thiese difffering traditions mixed up in her
Book of Fixed Stars.
Another point I would mention is that traces of the Egyptian and Babylonian constellations are found in various sources such as Teucer of Babylon, Manilius, Firmicus and in medieval sources such as Abu' Mashar, Michael Scot and Ibn Ezra. Although the Greek constellations eventually predominated the interest in the
Sphaera Barbarica persisted. Indeed there was some of a revival of interest (at least in terms of art) in the renaissance period.
The Roman astrologer Nigidius Figulus (1st century BCE) is supposed to have written two books on the constellations and their role in astrology. First a book on the Greek Constellations and a second on the Sphaera Barbarica. The books apparently discussed the use of the paranatellonta. Had these two books survived I think our understanding of early atttitudes to fixed stars and constellations would be much clearer.

I also think they might have definitively disproved the sceptics who now leap to the assumption that fixed stars were not important in early astrology because of the paucity of surviving sources.
