Trick at Mecone

It is unusual among Greek myths for being etiological, i.e. explaining the origins of an object or custom.

[1] 'Mecone' or 'Mekone' was identified in Classical times with Sicyon, though it is unknown if Hesiod recognized this identification.

[2] The story survives only in Hesiod's Theogony, with the exception of a brief reference to it in the works of Callimachus.

[1] As an act of revenge, Zeus hid fire from humankind, leaving them cold and shivering at night.

The story gives a mythological explanation (etiology) of the practice of sacrificing only the bones to the gods, while humans get to keep the edible meat and fat.
