The xenia motif in Roman mosaic is a still life motif consisting of a grouping of various items, mostly edible, representing a generous offering (a xenia) from a wealthy host to guests.
Typical elements of a xenia motif include game hanging from hooks, fish, baskets of fruit (often overturned), and the like.
Vitruvius lists specifically "poultry, eggs, vegetables, and other country produce".
Originally found in Latin literature, it was revived in the nineteenth century.
The 13th book of Martial's epigrams is entitled Xenia, and catalogs the foods that might be given to a departing guest at the Saturnalia.
