Of the new elements interwoven by Apuleius in the story of the transformations and adventures of Lucius of Patrae (Lucius of Madaura, he calls him, thus hinting, to the mingled awe and confusion of his readers, that the events had happened to himself), the fervid religious enthusiasm of the conclusion is no doubt historically the most important; but what has made it immortal is the famous story of Cupid and Psyche, which fills nearly two books of the _Metamorphoses_. With the strangeness characteristic of the whole work, this wonderful and exquisitely told story is put in the mouth of a half crazy and drunken old woman, in the robbers' cave where part of the action passes. But her first half-dozen words, the _Erant in quadam civitate rex et regina_, lift it in a moment into the fairy world of pure romance. The story itself is in its constituent elements a well-known specimen of the _märchen,_ or popular tale, which is not only current throughout the Aryan peoples, but may be traced in the popular mythology of all primitive races. It is beyond doubt in its essential features of immemorial antiquity; but what is unique about it is its sudden appearance in literature in the full flower of its most elaborate perfection. Before Apuleius there is no trace of the story in Greek or Roman writing; he tells it with a daintiness of touch and a wealth of fanciful ornament that have left later story- tellers little or nothing to add. The version by which it is best known to modern readers, that in the _Earthly Paradise_, while, after the modern poet's manner, expanding the descriptions for their own sake, follows Apuleius otherwise with exact fidelity.
