Cupid Proved a Fencer

Ah Cupid, I mistook thee:
I for an archer, and no fencer took thee.
But as a fencer oft feigns blows and thrusts,
Where he intends no harm,
Then turns his baleful arm,
And wounds that part which least his foe mistrusts;

So thou, with fencing art,
Feigning to wound mine eyes, hast hit my heart.
