In existographies, **Iamblichus** (c.245-325) (CR:2) was a Syrian philosopher, noted for existography work on Pythagoras.

## Overview

### Amicable numbers

It is known that Pythagoras (c.520BC), according to Iamblichus, knew about the 220 and 284 amicable number pair.^{[1]}

### Leucippus

In c.305, Iamblichus asserted that Leucippus was a member of some type of “school” that was contemporaneous with Pythagoras or his young students:

- “The members of this school, and particularly the earliest, who were contemporaries of Pythagoras and young students of his in his old age, Philolaus and Eurytus … Leucippus and Alcmaeon.”

## Quotes

### Quotes | By

The following are quotes by Iamblichus:

- “Hence, they call the
**monad**‘Prometheus’, the artificer of life, because, uniquely, it in no way outruns or departs from its own principle, nor allows anything else to do so, since it shares out its own properties.”- — Iamblichus (c.310),
*The Theology of Arithmetic*(pg. 38)

- — Iamblichus (c.310),

- “Likewise, they call the monad ‘chaos’, which is Hesiod's first generator, because chaos gives rise to everything else, as the
**monad**does. It is also thought to be both ‘mixture’ and ‘blending’, ‘obscurity’ and ‘darkness’, thanks to the lack of articulation and distinction of everything which ensues from it. Anatolius says that it is called ‘matrix’ and ‘matter’, on the grounds that without it there is no number. The mark which signifies the monad is a symbol of the source of all things. And it reveals its kinship with the sun in the summation of its name: for the word ‘monad’ when added up yields 361, which are the degrees of the zodiacal circle.”- — Iamblichus (c.305),
*Theology of Arithmetic*(pg. 39); cited by Kieren Barry (1999) in*The Greek Qabalah*(pgs. 65-66)^{[3]}
