A Frog proclaimed himself a physician. A Fox asked the Frog how he can cure others when he can’t cure his own wrinkled appearance.
Physician, heal thyself.
Aesop For Children (The Quack Toad)
An old Toad once informed all his neighbors that he was a learned doctor. In fact he could cure anything. The Fox heard the news and hurried to see the Toad. He looked the Toad over very carefully.
“Mr. Toad,” he said, “I’ve been told that you cure anything! But just take a look at yourself, and then try some of your own medicine. If you can cure yourself of that blotchy skin and that rheumatic gait, someone might believe you. Otherwise, I should advise you to try some other profession.”
Those who would mend others, should first mend themselves.
A frog once upon a time came forth from his home in the marsh and proclaimed to all the beasts that he was a learned physician, skilled in the use of drugs and able to heal all diseases. A Fox asked him, “How can you pretend to prescribe for others, when you are unable to heal your own lame gait and wrinkled skin?’
JBR Collection (The Frog and The Fox)
A Frog came out of his native marsh, and, hopping off to the top of a mound of earth, gave out to all the beasts around that he was a great physician, and could heal all manner of diseases. The Fox demanded why, if he was so clever, he did not mend his own blotched and spotted body, his stare eyes, and his lantern jaws.
Vulpes et Vermiculus
Emersus de sterquilinio, vermis coepit profiteri apud animantes se esse medicum summum, neque cedere Paeoni, deorum medico, usu et experientia artis. Quem rugis deformem et nutantem intuita, vulpes “Medice,” inquit, “teipsum curare prius atque ita profiteri artem debueras.”
Rana et Vulpes
Rana, paludibus valedicens, novo vivendi genere acquisito, in silvam gloriabunda sese tulit et, bestiarum coronis circumstipata, medicinae artem publice profitebatur et in herbis quae ad corpora curanda pertinent nobiliorem se vel Galeno vel Hippocrate esse clamitabat. Credula bestiarum gens fidem facile adhibebat, vulpe solummodo excepta. Quae sic glorianti irridebat, “Insulsum vagumque animal! Quid tam vana blatteras? Quid artem nobilem prae te fers, quam minime calles? Livida pallidaque illa tua labra respice! Quin domi abi et teipsum cura, medice! Deinde ad nos redeas, meliora forsan de te speraturos.” Nihil respondente rana sed tacitis secum gemente suspiriis, tota bestiarum cachinnis resonabat silva.
