Thank you, Contrabass. Your post is precisely what I had been seeking. I shall use it as a template, if that is acceptable to you.
The History of Nourjahad by Francis Sheridan, 1767
Schemzeddin, new ruler of Persia, seeks a new first minister, and thus turns to his childhood cohort Nourjahad. However, before Nourjahad is officially made minister, an angel visits him during the night, granting him inexhaustible riches and eternal life. Nourjahad is young and egotistical, and thus enjoys his new bounties without reserve. However, as soon as his temperament turns to sin, he is struck unconscious (the foil to the gifts). Read to discover how this both curse and blessing affects him when he finds a first love, and discovers a friend of infinite trustworthiness.
This novel is written during a time when books of the orient were quite popular in England, and when the "novel" was a novel, new concept (pun intended). This work is historically important in that regard, but what makes it a worthwhile read is its particular take on human nature, unlimited power, and sin. Additionally, dark humor on the subject of human desire and time travel (not exactly, but a similar concept) allow for entertainment and thinking points throughout.
This is a short read (I read it in an hour), and is available for free online, as it is in the public domain. An online text is available
