The peryton is said to have the head, neck, forelegs and antlers of a stag, combined with the plumage, wings and hindquarters of a large bird, although some interpretations portray the peryton as a deer in all but coloration and bird's wings. According to Borges, perytons lived in Atlantis until an earthquake destroyed the civilization and the creatures escaped by flight. A peryton casts the shadow of a man until it kills one during its lifetime, at which time it starts to cast its own shadow. A sibyl once prophesied that the perytons would lead to the downfall of Rome. In Borges' original Spanish edition, the word is given as peritio so the presumptive Latin original would be peritius, which happens to be the Latin name of the fourth month on the ancient Macedonian calendar. The connection of this, if any, to the peryton is unclear.
Perytons are found or used in modern literature and games.
Books and manga
Monsters called 'perytons' appear in Diane Duane's Young Wizards series of young-adult fantasy novels as minions of the archvillain of the series; while their appearance and nature is very different from the creatures describes by Borges, they still bear a number of conceptual similarities.
A peryton closely matching Borges's original description is a minor villain in The Cinnabar Box, a fantasy novel by Ilil Arbel. Uniquely, this incarnation of the monster can use and understand human speech.
The creatures also appear in Darkwell, a book in The Moonshae Trilogy, where a flock of perytons are among an army of evil monsters summoned by the book's main antagonist.
A herd of golden-furred perytons with poisonous antlers attack the main characters in the book while fleeing a dragon.

Science
The term peryton is also used for radio signals of terrestrial origin that mimic fast radio bursts, pulses that appear to be coming from outside of our galaxy. These perytons were found to be the result of premature opening of a microwave oven door, which releases a frequency-swept radio pulse, which mimics a fast radio burst, as the magnetron turns off.
