So reached they Kronion’s steep rock sunward-soaring.
There prophecy’s twin treasure gave his sire—
To hear his voice unswerving truth outpouring
First: then, when Heracles, that soul of fire,
Should come, when he, the Alkaïds’ seed renowned,
Should found his God-sire’s Feast thronged by all nations,
Of all world-games with chiefest honour crowned,
Then high on Zeus’s altar of oblations
A second oracle he bade him found.
