[NOTE 12.
"Took their coena at noon."—And, by the way, in order to show how little coena had to do with any evening hour (though, in any age but that of our fathers, four in the afternoon would never have been thought an evening hour in the sense implied by supper,)—the Roman gourmands and bons vivants continued through the very last ages of Rome to take their coena, when more than usually sumptuous, at noon. This, indeed, all people did occasionally, just as we sometimes give a dinner even now so early as four, P.M., under the name of a dejeuner à la fourchette. Those who took their coena so early as this, were said de die coenare—to begin dining from high day. Just as the line in Horace—"Ut jugulent homines surgunt de nocte latrones," does not mean that the robbers rise when others are going to bed, viz., at nightfall, but at midnight. For, says one of the three best scholars of this earth, de die, de nocte, mean from that hour which was most fully, most intensely day or night, viz., the centre, the meridian. This one fact is surely a clencher as to the question whether coena meant dinner or supper.]
