Then let no woman hence in man believe,
Or think a lover speaks but to deceive.
He, while ungratified desire is high,
Shrinks from no oath, no promise will deny;
Soon as his lust is satiate with its prize,
He spurns his vows and perjury’s curse defies.
 
[Nunc iam nulla viro iuranti femina credat,
nulla viri speret sermones esse fideles;
quis dum aliquid cupiens animus praegestit apisci,
nil metuunt iurare, nihil promittere parcunt:
sed simul ac cupidae mentis satiata libido est,
dicta nihil metuere, nihil periuria curant.]

Ariadne lamenting Theseus' faithlessness.

(Source (Latin)). Alternate translations:

Hear this, and wisdom learn, ye witless fair!
Ne'er let false man with empty oaths deceive,
No protestations of the sex believe!
Is there a wish their ardent souls would gain;
they swear, they promise, and at length obtain;
The wish obtain'd, they fearless break their word,
Nor plighted faith, nor solemn vows regard.
[tr. Nott (1795), # 61; ll. 173ff.]

Henceforth let woman; never trust the oaths that man shall make,
Nor ever more his honeyed speech within her bosom take!
While yet the fire of his desire is hot within his breast,
What will he not to woman swear, to heav'n what not protest?
But let her in an evil hour resign her maiden trust,
And yield the blossom of her youth to sate his selfish lust,
Then what recks he of lavish oath, or vow, or whisper'd pray'r?
He triumphs in his perjuries, and spurns at her despair.
[tr. T. Martin (1861)]

Henceforth let never woman trust an oath than man shall swear,
Nor count the tender speeches true his lying lips declare:
For when with lusting soul he yearns some object to enjoy,
No oath, no promise then he deems too sacred to employ;
But when his soul is sated, and his burning passion dies,
He fears to break no plighted vows, cares nought for perjuries.
[tr. Cranstoun (1867)]

Let not a woman trust, since that first treason, a lover's
Desperate oath, none hope true lover's promise is earnest.
They, while fondly to win their amorous humour essayeth,
Fear no covetous oath, all false free promises heed not;
They if once lewd pleasure attain unruly possession,
Lo they fear not promise, of oath or perjury reck not.
[tr. Ellis (1871)]

Now, let woman no more trust her to man when he sweareth,
Ne'er let her hope to find or truth or faith in his pleadings,
Who when lustful thought forelooks to somewhat attaining,
Never an oath they fear, shall spare no promise to promise.
Yet no sooner they sate all lewdness and lecherous fancy,
Nothing remember of words and reck they naught of fore-swearing.
[tr. Burton (1893)]

Now, now, let no woman give credence to man's oath, let none hope for faithful vows from mankind; for while their eager desire strives for its end, nothing fear they to swear, nothing of promises forbear they: but instantly their lusting thoughts are satiate with lewdness, nothing of speech they remember, nothing of perjuries care.
[tr. Smithers (1894)]

Henceforth let no woman believe a man's oath, let none believe that a man's speeches can be trustworthy. They, while their mind desires something and longs eagerly to gain it, nothing fear to swear, nothing spare to promise; but as soon as the lust of their greedy mind is satisfied, they fear not then their words, they heed not their perjuries.
[tr. Warre Cornish (1904)]

Hereafter let; no woman trust man's promises, or hope for faithful words; for when they wish to attain their desires, there is nothing they will not swear, no promise do they scruple to make: but once their desires have been satisfied, they fear no broken words and care nothing for their perjuries.
[tr. Stuttaford (1912)]

Never let maid believe a lover's oath;
Nor hope a man be faithful to his troth;
Long as men's hearts are spurred by keen desire,
No oath they shrink from and no promise spare;
Soon as their sated lust begins to tire
No oath they heed and nought for falsehood care.
[tr. Symons-Jeune (1923)]

Henceforth, no woman trust the oath of man,
No woman dream the word of man is true:
They, whensoe'er they lust for anything,
Swear every oath and every promise make,
But, when their eager lust is satisfied,
Nor reck of oaths nor promises regard.
[tr. MacNaghten (1925)]

Henceforth let never listening maid believe
Protesting man! When their false hearts conceive
The selfish wish, to all but pleasure blind,
No words they spare, no oaths unuttered leave.
But when possession cloys their pampered mind,
No care have they for oaths, no words their honour bind.
[tr. Wright (1926)]

From this hour
may no woman believe what men say, for men (minds set upon a single end) will promise everything,
but once the shrewd mind satisfies its passion, it plunges forward (the broken promise merely words that trail behind tall bravery).
[tr. Gregory (1931)]

Let no woman ever believe any oath that a man swears,
or ever expect him to keep faith with his fine speeches!
When they want something, when they are anxious to get it,
they take oaths without fear, and pour out promises freely;
but just as soon as their hot desire is sated,
none of their lies & deceptions ever disturb them.
[tr. C. Martin (1979)]

From now on let no woman believe a man's sworn promises.
From now on let no woman hope a man's talk is true.
So long as their desiring minds are eager to get something,
they swear to anything. No promise do they spare.
But as soon as the lust in their desirous intent is gratified,
they remember nothing they said, they care nothing for their lies.
[tr. Banks (1997)]

Now, no woman should believe a man’s pledges,
or believe there’s any truth in a man’s words:
when their minds are intent on their desire,
they have no fear of oaths, don’t spare their promises:
but as soon as the lust of their eager mind is slaked
they fear no words, they care nothing for perjury.
[tr. Kline (2001)]

Henceforth let no woman trust a man's sworn promise,
or hope that he'll ever be true to his given word,
for as long as his lustful heart is bent on possession
he'll shrink from no oath, stop short at no promises,
but the moment hte urge of his ardent mind is sated
he forgets all he's said, breaks oaths without a tremor.
[tr. Green (2005)]

Now already let no woman trust a man swearing,
let none hope that the speeches of man are faithful,
for whom while the desiring mind is eager to grasp something,
They fear to swear nothing, they spare to promise nothing.
But as soon as the lust of the desiring mind has been satisfied,
They feared the words as nothing, they care for the false oaths not at all.
