And when Hephaestus heard the grievous tale, he went his way to his smithy, pondering evil in the deep of his heart, and set on the anvil block the great anvil and forged bonds which might not be broken or loosed, that the lovers might bide fast where they were.

So they two went to the couch, and lay them down to sleep, and about them clung the cunning bonds of the wise Hephaestus, nor could they in any wise stir their limbs or raise them up. Then at length they learned that there was no more escaping.
