Divination, or predicting, with numerology; as practiced by Greeks and Chaldeans: "The Greeks would use arithmomancy to analyze the names of warring enemies and so determine their numerical values and from this they would predict the results of a battle with this process."

"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 number values of countries, individuals, and situations; all of which represented certain characteristics used for predicting future events."
