The God whom Artists always grace,
By giving him a double face;
The food divine, that’s eat on high,
By all the inmates of the sky;
Also the Liquor drank above,
Which Hebe hands, to mighty Jove;
He, who for fair Calypso’s smile,
Forgot his wife, and native isle;
Now Thetis’ son, who chose the strife,
Of warlike fame, instead of life;
That island, where we’re always told,
The brass Colossus stood of old;
The time, no efforts can regain,
Tho’ oft we spend its hours in vain.
Take the first letters and they’ll tell
A month, when firing pleases well.

Good luck.
