Geffrey Whitney, A choice of emblemes (Leiden, 1586)
A bird (swallow) flies to its young which sits in the nest on top of a statue of Medea, killing her children

Ei, qui semel sua prodegerit, aliena credi non oportereLatin
He who has once squandered his own ought not to be trusted with another.
Within an elaborate woodcut border of foliage and floral ornament, a framed scene shows a classical architectural interior: a statue standing on a pedestal in an arched niche between columns. The statue is a woman in flowing drapery holding a raised dagger or sword in one hand and clutching a naked infant against her breast with the other. Above, near the top of the arch, a swallow flies toward a nest built on the cornice.

MEDEA loe with infante in her arme, Whoe kil'de her babes, shee shoulde haue loued beste: The swallowe yet, whoe did suspect no harme, Hir Image likes, and hatch'd vppon her breste: And lefte her younge, vnto this tirauntes guide, Whoe, peecemeale did her proper fruicte deuide. Oh foolishe birde, think'ste thow, shee will haue care, Vppon thy yonge? Whoe hathe her owne destroy'de, And maie it bee, that shee thie birdes should spare? Whoe slue her owne, in whome shee shoulde haue ioy'd. Thow arte deceauide, and arte a warninge good, To put no truste, in them that hate theire blood.
Behold Medea with an infant in her arm, who killed her babes, whom she should have loved best. Yet the swallow, who suspected no harm, took a liking to her image and hatched upon her breast; and left her young in this tyrant's keeping, who tore her own offspring piecemeal apart. Oh foolish bird, do you think she will take care of your young? She who has destroyed her own? And can it be that she should spare your birds, who slew her own, in whom she should have rejoiced? You are deceived, and you are a good warning to put no trust in those that hate their own blood.
MEDEÆ statua est: natos cui credis Hirundo? Fer aliò: viden' hæc mactet vt ipsa suos?
It is a statue of Medea: to whom do you entrust your young, Swallow? Carry them elsewhere: do you see how she herself slaughters her own?

Suggested relationships between this emblem and adages in Erasmus’ Adagia.
Both motto and adage turn on the logic of 'semel' — once a man has shown what he is (cheated once / squandered his own once), no further trust should be placed in him; the emblem's closing moral, 'put no truste in them that hate theire blood', is the same lesson of prudent distrust based on past conduct.
The motto's key verb 'prodegerit' echoes Erasmus' proverbial figure on wasteful squandering ('si quid prodegeris'), which he applies to those who dissipate their substance and must later suffer for it — the same figure of the prodigal unfit to be trusted.
Erasmus glosses the adage as a warning 'not to trust ourselves to an unknown person, but to beware of him as of a wolf'; the swallow's fatal credulity before the murderous Medea dramatizes exactly this warning against misplaced trust in a cruel other.
