Earthly Delights is an Apple II text adventure created by Roger Webster and Daniel Leviton and published by Datamost in 1984.
The uncle writes that pleasures and rewards will come to the player if they keep the picture, and exhorts them not to sell it.
When a stranger approaches the player offering an enormous sum for the work, their suspicions are aroused and the adventure of Earthly Delights begins.
This allusion is supported by the painting's depiction on the cover, which mimics the mountainous landscape of Parrish's Canyon and female subject in flowing dress common in his works.
Though Parrish never created a piece named Earthly Delight, Dutch artist Hieronymus Bosch painted a triptych named The Garden of Earthly Delights in the early 16th century.
