Note 12 — BOOK II.
Rowland Smith translation
εὑφημοῦντες. Especial care was taken during a sacrifice, that no inauspicious or frivolous words were uttered by any of the bystanders; hence the admonitions of the priest,—εῦφημεῖτε, εὐφημία, σιγᾶτε, σιωπᾶτε, favete linguis, and others; for improper expressions were thought not only to pollute the sacred act, but to be unlucky omens.
