Perry 117: The Camel who Wanted Horns

L'Estrange: A Camel Praying for Horns
It stuck filthily in the Camel’s Stomach, that Bulls, Stags, Lions, Bears, and the like, should be armed with Horns, Teeth, and Claws, and that a Creature of his Size should be left naked and Defenceless. Upon this Thought he fell down upon his marrow-bones, and beg’d of Jupiter to give him a pair of Horns, but the Request was so ridiculous, that Jupiter, instead of horning him, order’d him to be cropt, and so punish’d him with the Loss of his Ears, which Nature had allow’d him, for being so unreasonable as to ask for Horns, that Providence had never intended him.
The Boundaries of Heaven are in such manner distributed, that every living Creature has its share; beside, that to desire Things against Nature, is effectually to blame the very Author of Nature itself.

Boothby: Avianus. The Camel.
The restless discontented mind
Change for the worse will often find.
A Camel begg'd of Jove that he
One of the horned tribe might be;
Who, to reward his foolish prayers,
Decreed that he should lose his ears.
