The Lion, the Boar and the Vultures
fable by Aesop

The Lion, the Boar and the Vultures is sometimes counted among Aesop's Fables and warns against quarrels of which others will take advantage. It is numbered 338 in the Perry Index.
One man's loss is another man's gain
The fable only existed in Greek sources formerly and concerns a lion and boar who fight each other to be the first to drink from a spring. Observing vultures gathering to swoop on the loser, the two fierce animals decide that it is better to have friendly relations rather than be eaten by such vile creatures. The story appeared in few of the main fable collections but was given popularity during the Renaissance by being included among the emblems of Andrea Alciato under the heading "One man's loss is another man's gain" (ex damno alterius, alterius utilitas). The Latin quatrain accompanying the illustration does not mention the cause of the quarrel but concludes that the victor's glory will belong to the one that gets the spoil.
Still another moral was given the story by Arthur Golding in his manuscript A Moral Fabletalk later in the 16th century. There the religious author, observing the behaviour of the waiting vulture, concluded that hope is often deceived and should only be placed in God. A century later, at the end of several civil conflicts, Roger L'Estrange's reflection was ultimately sceptical: "There are several sorts of men in the world that live upon the sins and the misfortunes of other people…for the wrangling of some is the livelihood of others". He lists those who gain as lawyers, religious divines and soldiers.
This brief starts where responsible research should: with the source description of “The Lion, the Boar and the Vultures” as fable by Aesop. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as fable by Aesop. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 23, 2024. The linked authority identifier is Q54309223. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
