In Roman Era dwellings (particularly those of the wealthy), triclinia were standard issue. A triclinium is a room characterized by 3 beds surrounding a table. Used to entertain company, the hosts and guest would recline on the beds while feasting on the flesh of lesser beasts and other refreshments. For an example of an accurately reconstructed triclinium, visit the Museum of Archeology in Arezzo, Italy. Archaeology or sometimes in American English archeology (from the Greek words αρχαίος = ancient and λόγος = word/speech) is the study of human cultures through the recovery, documentation and analysis of material remains, including architecture, artefacts, biofacts, human remains, and landscapes. ... Arezzo is a city in central Italy, capital of the province of the same name, located in Tuscany. ...
It is thought that the Last Supper was at a triclinium.
The plan of the house includes features such as a large peristyle and triclinium, and a fish pond (piscina) that were common in the houses of the pro-Roman cultured elite in the Greek east.
In this connection the author notes that the triclinium of the House of the Triumph of Dionysos at Antioch has the same subject for the entrance panel and that the room itself is about the same width (8.7 m at Antioch; 8.5 at Paphos).
The triclinium's arbor carpet, the subject of the following chapter, reveals the surprisingly close parallels to a North African type produced from the mid-second to fifth centuries, with the difference that the Paphian pavement employs upright vines rather than ones growing from craters placed diagonally (241-243).
The triclinium, or dining room, took its name from the three couches on which family members and their guests lounged to take their meals.
Each couch was wide enough to accommodate three diners who reclined on their left side on cushions while some household slaves served multiple courses rushed out of the culina, or kitchen and others entertained guests with music, song or dance.
Each of the three couches in the triclinium carried significant social standing, as did the three positions on the couch.
