since they had met.

Then Perseus went out, and up to the hall of Polydectes; and
underneath the goat-skin he bore the Gorgon's head.

And when he came into the hall, Polydectes sat at the table-head,
and all his nobles and landowners on either side, each according to
his rank, feasting on the fish and the goat's flesh, and drinking
the blood-red wine. The harpers harped, and the revellers shouted,
and the wine-cups rang merrily as they passed from hand to hand,
and great was the noise in the hall of Polydectes.

Then Persons stood upon the threshold, and called to the king by
name. But none of the guests knew Perseus, for he was changed by
his long journey. He had gone out a boy, and he was come home a
hero; his eye shone like an eagle's, and his beard was like a
lion's beard, and he stood up like a wild bull in his pride.

But Polydectes the wicked knew him, and hardened his heart still
more; and scornfully he called -

'Ah, foundling! have you found it more easy to promise than to
fulfil?'

'Those whom the Gods help fulfil their promises; and those who
despise them, reap as they have sown. Behold the Gorgon's head!'

Then Perseus drew back the goat-skin, and held aloft the Gorgon's
head.
