Figure D11 TONANS
Northward to an onyx-marbled court
Whose floor is an enormous ruddy eye.
To JUPITER devote, and these his sport:
Sulphurous IO, maddened by the fly,
EUROPA’S ocean with its icy sky,
Remote CALLISTO, beauteous, rejoice
In thy Dian: and, borne by eagle high,
The handsome GANYMEDE: for Zeus’s choice
Is ofttimes like his thunder, in falsetto voice.
