"Curious - is there any place to get information on the Zodiac across the four worlds? 777 gives their Hebrew names as Heavens in Assiah, and the Color Scales, but I can't find any divine names in Yetzirah, Briah or Atziluth. Any ideas? "

So what you really maen is "The Zodiac in Four Worlds," not astrology therein.

The information is all available, but often not organized very well. 776 1/2, however, lays it all out clearly.

There are two separate sets of the Divine Names (the Atziluthic expression). One is the Divine Name of the ruling planet (e.g., for Virgo and Gemini is is Elohim Tzabaoth). The other is the permutation of Tetragrammaton. (See 776.5, Cols. 301-302.)

The archangels (or Briatic expression) are the names listed in 777 as Geomantic Intelligences. For example, for Virgo it is HMLIAL, Hamaliel. (See 776.5 Cols. 303-304.)

For Yetziratic names - thes are legion. There are multiple hierachies and interrelating angelic names etc. In 776.5 these are listed in columns 411-424, and include Spirits (or Genii) of the respective Pths, Angels Ruling the Signs, their Lesser Assistants, Angel Lords by Triplicity (Day & Night expressions), and angels differentiated by decanate and also by pentade.

The Words of Power in Assiah are the Hebrew names of the signs (776.5, Col. 501).
