Divination, or predicting, with numerology; as practiced by Greeks and Chaldeans: The Greeks would use arithmomancy to analyze the names of their warring enemies in order to determine their numerical values, and with this process, they thought they could predict the results of battles.

The Chaldeans divided their alphabet into three sections of seven letters and made a symbolic link to the seven planets to determine various arithmomancies which included numerical values of countries, individuals, and situations, all of which represented certain characteristics used for predicting future events.
