Ovid, "Metamorphoses," Book III, Narcissus and Echo

When Jove, dispos'd to lay aside the weight
Of publick empire and the cares of state,
As to his queen in nectar bowls he quaff'd,
"In troth," says he, and as he spoke he laugh'd,
"The sense of pleasure in the male is far
More dull and dead, than what you females share."
Juno the truth of what was said deny'd;
Tiresias therefore must the cause decide,
For he the pleasure of each sex had try'd.

...

And he declar'd for Jove: when Juno fir'd,
More than so trivial an affair requir'd,
Depriv'd him, in her fury, of his sight,
And left him groping round in sudden night.
But Jove (for so it is in Heav'n decreed,
That no one God repeal another's deed)
Irradiates all his soul with inward light,
And with the prophet's art relieves the want of sight.

...

The tender dame, sollicitous to know
Whether her child should reach old age or no,
Consults the sage Tiresias, who replies,
"If e'er he knows himself he surely dies."
Long liv'd the dubious mother in suspence,

'Till time unriddled all the prophet's sense.
