Plural of 'biclinium'; a pair of couches or benches arranged side-by-side, especially as used in ancient Roman dining.
From Latin 'bi-' (two) plus 'clinium' (couch or bed). In Roman times, this seating arrangement was standard for formal meals where diners would recline while eating.
Roman dinner parties were wild—guests would lounge sideways on these couches while servants brought course after course, and the arrangement of biclinia told you exactly where you ranked in the social hierarchy of the dinner party.
