Only she is chaste whom none has invited - Ovid

Quod male fers, adsuesce, feres bene.

The god of Delos, proud in victory,
Saw Cupid draw his bow's taut arc, and said:
'Mischievous boy, what are a brave man's arms
To you? That gear becomes my shoulders best.
My aim is sure; I wound my enemies,
I wound wild beasts; my countless arrows slew
But now the bloated Python, whose vast coils
Across so many acres spread their blight.
You and your loves! You have your torch to light them!Let that content you; never claim my fame!'

And Venus' son replied: 'Your bow, Apollo,
May vanquish all, but mine shall vanquish you.
As every creature yields to power divine,
So likewise shall your glory yield to mine.

Fas est ab hoste doceri.
One should learn even from one's enemies.
