A youtube video on numerology started playing and I almost switched it off. I thought about how ridiculous it was but I thought it would be amusing to listen. Well, the narrator said something of interest to me about the numbers 1-9 and how Pythagorus also used this same numbering system.

Pythagoras influenced other ancient Greek authors such as Socrates and Plato. He believed that everything has sound and therefore everything is a number. We can't understand Pythagoras until we understand the myth that inspired him... Orpheus.
