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 his 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".
Xenia motifs are typically found in reception rooms.
The word xenia is Greek, and means 'hospitality'; in Latin, it came to mean presents for guests, and later presents in general. It also came to include a class of epigrammatic inscription attached to the presents, xenia epigrams.
