Etymology
The term arithmancy is derived from two Greek words – arithmos (meaning 'number') and manteia (meaning 'divination'). "Αριθμομαντεία" (arithmomanteía) Arithmancy is thus the study of divination through numbers. Although the word "arithmancy" dates back to the 1570s, the word "numerology" was not recorded in English before c. 1907.
