| "Known are their laws; in harmony unroll |
| The nineteen-orbed cycles of the Moon. |
| And all the signs through which Night whirls her car |
| From belted Orion back to Orion and his dauntless Hound, |
| And all Poseidon's, all high Zeus' stars |
| Bear on their beams true messages to man." |
| Poste's Aratus. |
