The phrase sacra mensae appears in only a select number of instances from the first century a.d. onwards. This paper seeks to demonstrate that references to sacra mensae are not coincidental, and that they were employed deliberately by authors such as Valerius Maximus and, after him, Quintilian, Tacitus and Seneca, based on an assumed shared understanding of their significance on the part of Roman audiences. Although it appears across a variety of literary works and in a range of contexts, the (...) phrase does not seem to have been used in reference to a specific rite or rites performed at the table. Instead, sacra mensae appears to have been used primarily in a metaphorical sense, designed to epitomize the customs and respect attached to dining in Roman culture. Religion certainly played an important part in creating the aura surrounding the table, which was subject to various rituals and superstitions that were discussed by ancient authors. However, beyond the sphere of religion there was the equally important social emphasis on dining, which enforced notions of conviviality and personal obligation between hosts and guests. Disregard of such traditions came to be identified as a hallmark of tyranny, which provided the writers of the Principate with an opportunity to use the sacra mensae as a powerful literary device against those who failed to respect established customs of hospitality.
