triclinium

Triclinium comes from Greek triklinos: tri- (three) + klinē (couch, bed — the same root as clinic, recline, and incline). The room of three couches. In the Roman house, the triclinium was the formal dining room, arranged with three dining couches (triclinia) positioned around three sides of a low central table. Diners reclined on their left sides, leaning on their left elbows, reaching for food with their right hands. Proper Romans ate lying down. Standing to eat was for servants and barbarians.

The arrangement of the three couches was socially precise. The lectus medius — the middle couch, facing the door — was where the host sat. The lectus summus (highest couch) held the most honored guests; the lectus imus (lowest) held the least. Within each couch, position mattered: the imus in imo (lowest place on the lowest couch) was for the social inferior. Being invited to dinner and placed incorrectly was an insult that could end a friendship. The physical room was a map of the social order.

The triclinium appears throughout Latin literature as the stage for what Romans called convivium — the 'living together' that a proper dinner accomplished. Petronius's Satyricon describes the freedman Trimalchio's vulgarly excessive feast in his triclinium. Pliny the Younger writes letters describing intimate literary dinners in his. The Roman triclinium was not just where food was consumed but where alliances were made, poetry was performed, philosophy was disputed, and reputations were won and lost.

When Roman culture fell, the triclinium fell with it. Medieval Europe ate at trestle tables in halls, sitting upright. The reclining diner was forgotten for a thousand years. But the formal dining room — the room set apart from kitchen and work for the serious social business of eating together — survived in every subsequent European culture. The layout changed; the social function endured. Every formal dining room in the world is a distant heir of the Roman triclinium.
