Rules.

Caravaggio, Bacchus, 1595

Come boy, and pour for me a cup

Of old Falernian. Fill it up
With wine, strong, sparkling, bright, and clear;
Our host decrees no water here.
Let dullards drink the Nymph's pale brew,
The sluggish thin their blood with dew.
For such pale stuff we have no use;
For us the purple grape's rich juice.
Begone, ye chilling water sprite;
Here burning Bacchus rules tonight!
