The Cult
No temple ever housed the One, and that is the point: cult attaches to gods of place, and Hén is prior to place. What antiquity offers instead is one devout community and one devotional practice. The early Pythagoreans, who held number to be the substance of things, treated the monad with religious seriousness: initiates swore the oath of the tetraktys — by the one ‘who handed down to our generation the tetraktys, which contains the fount and root of ever-flowing nature’. Neoplatonism then made the principle an object of addressable longing: Plotinus taught the soul's return to the One as its only true eros, and claimed to have arrived there four times. Later mystics and modern devotees who venerate unity are building on that Neoplatonic piety — not on any ancient temple, priesthood, or festival, none of which ever attached to the name.
