The Monkey And The Dolphin

The primary moral is "One falsehood leads to another." The monkey's first lie—claiming to be an Athenian—forced him into a second lie about noble birth, and then a third about knowing Piraeus. Each deception required a bigger one to support it, until the entire chain collapsed. The fable warns that dishonesty is structurally unstable: the more you lie, the more likely you are to be caught.

A Greek ship bound for Athens wrecks near Piraeus. Dolphins rescue the passengers, and one dolphin mistakes a pet monkey for a human. The monkey rides on the dolphin's back and falsely claims to be a noble Athenian citizen. When the dolphin asks if he knows Piraeus—the famous port of Athens—the monkey says "Piraeus is my very best friend," revealing he thinks it is a person, not a place. The dolphin, realizing he has been deceived, dives and abandons the monkey.

The Monkey and the Dolphin is catalogued as Perry Index 73 (Latin title: Delphinus et Simius). The Perry Index is the standard scholarly classification for Aesop's fables, compiled by Ben Edwin Perry in his 1952 work Aesopica. The fable also appears as number 191 in Townsend's popular English translation and as Book IV, Fable 7 in La Fontaine's French adaptation.

The dolphin's question is a cleverly disguised test. Piraeus is the main port of Athens—any real Athenian would recognize it immediately as a place. By asking casually whether the monkey "visits Piraeus," the dolphin gives the monkey a chance to prove his claimed identity. When the monkey responds that Piraeus is his "very best friend," he reveals total ignorance of Athens and exposes all his previous claims as lies.

The fable teaches children three important lessons. First, honesty matters—the monkey would have been safe if he had simply told the truth. Second, lies snowball—one small lie forced him into bigger lies that he could not sustain. Third, pretending to be something you are not usually backfires, because sooner or later someone will ask a question you cannot answer. The story shows that being truthful, even when it seems less impressive, is always the wiser choice.

In ancient Greece, dolphins were considered among the most intelligent and benevolent sea creatures. They were sacred to Apollo and Poseidon, and Greek mythology includes several stories of dolphins rescuing drowning sailors—most famously the poet Arion. Aesop draws on this cultural reputation to cast the dolphin as a wise and discerning rescuer, someone capable of detecting the monkey's fraud through a simple, well-placed question.

Yes, partly. Ancient Greeks genuinely kept pet monkeys—they were imported as exotic curiosities and sometimes taken aboard ships. The detail about dolphins rescuing shipwrecked sailors also reflects real Greek belief and legend. Aesop combines these authentic cultural elements with the fictional dialogue to create a story that would have felt plausible to ancient audiences, making the moral lesson about dishonesty land with greater force.

Several Aesop fables explore related themes of deception, pretension, and unmasked fraud. The Wolf and the Lion shows how stolen gains can be lost to a stronger force. The Fox and the Crow demonstrates how flattery exploits vanity. The Quack Toad features an animal whose false claims of expertise are exposed by a single pointed question, and The Boy Bathing warns about the consequences of reckless behavior near water.
