IN LESBIAM CAT. EP. 76.
Huc est mens deducta tua, mea Lesbia, culpa,
Atque ita se officio perdidit ipsa suo.
Ut jam nec bene velle queam tibi, si optima sias:
Nec desistere amare, omnia si facias.
ENGLISHED.
By thy fault is my mind brought to that pass,
That it its office quite forgotten has:
For be'est thou best, I cannot wish thee well,
And be'est thou worst, then I must love thee still.
Richard Lovelace
