Bulls and bears, in stock, stars, and poetry

Bulls and bears, in stock, stars, and poetry. During the South Sea Bubble, 300 years ago:

COME, fill the South Sea goblet full;
The gods shall of our stock take care;
Europa pleased accepts the Bull,
And Jove with joy puts off the Bear. 

Alexander Pope, “An Inscription upon a Punch-Bowl, In the South Sea Year, for a Club: Chased with Jupiter Placing Callisto in the Skies, and Europa with the Bull”
