"In Cocaigne" by Clark Ashton Smith

From here on out, the rest of the stories under the tag of Poseidonis are actually a collection of miscellaneous one-offs of lost lands and lost races in a broadly similar vein as Atlantis or Lemuria or Mu.

Cocaigne is a land of plenty in medieval myth, an imaginary place of extreme luxury and ease where physical comforts and pleasures are always immediately at hand and where the harshness of medieval peasant life does not exist.

No relationship to the drug cocaine, despite the similarity of pronunciation. Cocaigne is from the French, cocaine is from the Quechua word 'kúka'. Not even remotely related language families.

The picture used is "Das Schlaraffenland" (1567) by Pieter Brueghel the Elder.
