There is a town Canobus, built upon
The earth's fair margin at the mouth of Nile
And on the mound washed up by it; Io, there
Shall Zeus give back to thee thy perfect mind,
And only by the           and the touch
Of a hand not terrible; and thou to Zeus
Shalt bear a dusky son who shall be called
Thence, Epaphus, _Touched_.
