Persistence
"Having four eyes in the parts before and in the parts behind, two of them closing as in sleep; and upon the shoulders four wings, two in the act of flying, and two reposing as at rest. And the symbol was, that Cronus whilst he slept was watching, and reposed whilst he was awake. And in like manner with respect to the wings, that he was flying whilst he rested, yet rested whilst he flew... and there were also two wings upon the head, the one as a symbol of the intellectual part, the mind, and the other for the senses."
- Sanchuniathon, born circa 1400 BCE in Berytus, Phoenicia (on the land of present day Lebanon)
