Chaldea

A country that existed between the 10th and 6th centuries BCE; located in southeastern Mesopotamia (Iraq); inhabited by the Chaldeans, who were known for their knowledge of astronomy and astrology.

From the Ra Contact: One of the lands where there were entities who, “from old,” had received the data (had inherited ancient understandings) for which they called having to do with the heavens; these entities developed astrologically based teachings from which the Minor Arcana derived and which became one of the origins of the tarot.
