The Triclinium is a circle of three couches, cline signifying couch: the ancients used to recline upon couches. And the Architriclinus is the one at the head of the Triclinium, i. e. the chief of the guests. Some say that among the Jews, He was a priest, and attended the marriage in order to instruct in the duties of the married state.
