Read the passage from The Odyssey - Teiresias. But anguish lies ahead;
the god who thunders on the land prepares it,
not to be shaken from your track, implacable,
in rancor for the son whose eye you blinded.
One narrow strait may take you through his blows:
denial of yourself, restraint of shipmates.
When you make landfall on Thrinakia first
and quit the violet sea, dark on the land
you'll find the grazing herds of Helios
by whom all things are seen, all speech is known.
Avoid those kine, hold fast to your intent,
and hard seafaring brings you all to Ithaka.
But if you raid the beeves, I see destruction
for ship and crew.
