Note 555 — LIFE OF BRUTUS.
George Long translation
Kaltwasser has a note on the Roman practice of an invited guest taking his shadows (umbræ) with him. Horace alludes to the practice (i. Ep. 5, 28),
——“locus est et pluribus umbris.”
Plutarch discusses the etiquette as to umbræ in his Symposiaca (book vii. Qu. 6).
