The Chaldean Order is the ancient and traditional way of ordering the seven planets according to their relative speeds as seen from Earth. The order is:
This is order is so ubiquitous in traditional astrology that authors have no need to remind their readers, in the same way that we do not need to be told that Tuesdaty follows Monday. In other words, when the seven planets are mentioned, the Chaldean Order is implicit unless specified.

Chaldean Order in the Tarot
The Tarot appeared in Europe at a time when studying anything relating to Hebrew could result in a death sentence, so sources had to be disguised. Secret Societies used tarot to their own ends and changed the priority from the 22 letters to the numbers 1 to 10 on the Kabbalistic Tree of Life. The natural order of the planets in the 22 letters were lost/altered to suit the needs of each Secret Society. For example, the Golden Dawn transposed Strength with justice in order to make things fit better on the Tree of Life.
The Chaldean order appears in the Sephiroth and the Minor Arcana starting with
- 3 Saturn
- 4 Jupiter
- 5 Mars
- 6 Sun
- 7 Venus
- 8 Mercury
- 9 Moon
