A 17th Century Book

1
In Les Cahiers Astrologiques No. 110 May-June 1964, Gustave-Lambert Brahy is reviewing a book from Joseph de Tertius (Terzi) "De Gradu Horoscopante" (1690)
What is interesting is to look at some 'tools', astrologers of the 17th Century were using to cast a chart.
It shows some Tables similar to our House of Tables (Regiomontanus) and several tables to calculate the planetary hours, the aspects, fixed stars positions, faces and terms every day.
Another table gives the planetary dignities and exaltations with the definitions of the terms, faces, triplicities and the qualities of the 28 Lunar Mansions.
Concerning the Fixed Stars, contrary to what modern astrologers who use the longitudes of the Stars, they considered the Heliacal rising more important and very detailed explanations are given to locate them in the Signs. (when it first becomes visible above the eastern horizon at dawn just before sunrise thus becoming "the morning star", after it has spent a season behind the sun rendering it invisible.)

Ouranos
Blessings!

That is effectively what concerned the ancient Babylonians too.
