A POEM IN TWELVE CANTOS.

Pind. Pyth. x.
He can never set foot in the bronze heavens; but whatever splendor we mortals can attain, he reaches the limit of that voyage. Neither by ship nor on foot could you find [30] the marvellous road to the meeting-place of the Hyperboreans— Once Perseus, the leader of his people, entered their homes and feasted among them, when he found them sacrificing glorious hecatombs of donkeys to the god.

COUNTERTURN 2 [25-30]

and if he's also lived to see

his young son

duly crowned

with Pythian garlands.

∂ The bronze sky is beyond

his reach forever, but he has found

all the happiness

our mortal race can come to.

For neither on shipboard

nor by any journey made on foot

would you ever discover the miraculous way to the Hyperboreans.



STAND 2 [31-36]

With them Perseus, lord of the People, once feasted,

entering their houses. He had come upon them

while they were offering

hekatombs of asses to glorify Apollo,

who delights in their perpetual feasts and hymns

and is amused by the shrill impiety of their brutes.
