Hercules with his club fighting the HydraAI-generated

Telcuyde estre à repos, à qui vient grand affaire.
Emblem 99. He who thinks himself at rest is the very one to whom great trouble comes.AI-generated
A framed woodcut showing a rocky landscape with water in the background. At the right stands a nude, muscular male figure (Hercules) striding forward, a lion-skin or cloak draped over his shoulder and back, raising a club in both hands above his head. At the left, facing him, crouches a many-headed serpentine beast (the Hydra) with a dog- or lion-like body, clawed feet and a long coiled tail; numerous long snaky necks with open jaws and forked tongues rise and twist from its shoulders. One severed or drooping head lies near the ground between them.

QVãd Hercules, apres plusieurs cõquestes,Cuydoit auoir repos de ses labeurs,Hydra suruint auecques ses sept testes:Renouuelant ses trauaulx & malheurs.Quand par vertu auons acquis honneurs,Pensant auoir tousiours paix assouuie,Quelque meschant suruiendra par enuie,Pour nous donner plus que deuant affaire:Tel trauail n'eut Hercules en sa vie,Ne tel danger, que pour Hydra deffaire.
When Hercules, after many conquests, thought he would have rest from his labours, the Hydra came upon him with its seven heads, renewing his toils and misfortunes. When by virtue we have won honours, thinking we have peace fully secured forever, some wicked person will come along out of envy to give us more trouble than before: Hercules had no such labour in his life, nor such danger, as in destroying the Hydra.

Suggested relationships between this emblem and adages in Erasmus’ Adagia.
The emblem's picture (Hercules clubbing the many-headed Lernaean Hydra, with one head already severed) and its moral — that trouble renews itself just when one expects rest — are exactly the matter of Erasmus's 'Hydram secas', which explains Hercules' struggle with the regrowing heads as the figure for removing one evil only to meet many more (loci: Malum conduplicatum aut renovatum).
The subscriptio's theme — that after virtuous labours and won honours some envious wretch brings fresh toil — echoes Erasmus's great essay on the Labours of Hercules, where he complains that those who undertake Herculean toils for the common good reap envy rather than rest or thanks.
Shares the emblem's precise point that one hardship is immediately succeeded by a new one just when the struggle seemed over; no textual borrowing, only the common commonplace of 'malum conduplicatum aut renovatum'.
