What sets Pythagorean Numerology apart
Pythagorean numerology is the system built on one table: the 26 letters of the Latin alphabet written out in rows of nine, so A to I is 1 to 9, J to R is 1 to 9, and S to Z fills 1 to 8. This is the table behind the Expression, Soul Urge and Personality numbers. Its name credits Pythagoras, but the table is modern, and the Greek philosopher left no such letter chart.
- Table: A J S = 1, B K T = 2, C L U = 3, D M V = 4, E N W = 5, F O X = 6, G P Y = 7, H Q Z = 8, I R = 9
- Rows: three rows of nine, the last row ending at 8
- Origin: a modern table named for Pythagoras, not found in his own period
- Alternative: the Chaldean system uses values 1 to 8 and keeps 9 apart
Often mistaken for something else: The Chaldean system gives letters values 1 to 8 by sound; the Pythagorean table runs in alphabet order.
