I like astrology, but I don’t think tarot cards are necessary. Why do people use tarot cards for astrology?

Alex Sumner’s answer:

(A2A) Astrologers do not necessarily use Tarot cards: Tarot readers might however use Astrology. For example, relating a Tarot card to an associated Astrological meaning might help a Tarot reader interpret a given tarot spread.

In the late 19th century, the Hermetic Order of the Golden Dawn taught that because there are 22 major arcana in the Tarot, they can be allotted to the 12 signs of the Zodiac, 7 planets, and 3 of the Elements (Air, Water and Fire). The symbolism does actually make sense, e.g. “Justice” = Libra; “The Sun” = the Sun; “Death” = Scorpio (because Scorpio is equivalent to the 8th House, which is the House of Death); etc.

Furthermore, the Golden Dawn taught that the suits of the Minor Arcana correspond to the four astrological Triplicities; whilst there is a method of assigning the individual cards to the Zodiac which aids in clarifying their meaning.

The Six of Wands: Victory!
This card, for example, is associated with the second decan of Leo and the planet Jupiter, in the Golden Dawn system.

I say Astrologers do not necessarily use Tarot cards, but of course they may choose to do so nevertheless. One of the things I like to do is to do a Horary Astrological figure at the same time as doing a Tarot reading, on the basis that a Horary chart drawn up for the Time, Date and Place of a reading ought to corroborate the Tarot cards, or perhaps the cards might supply the details of how to interpret specific features of the chart.
