Note 2465 — BOOK XXII. THE PROPERTIES OF PLANTS AND FRUITS.
John Bostock translation
Festus says the “verbenæ,” or pure herbs, were called “sagmina,” because they were taken from a sacred (sacer) place. It is more generally supposed that “sagmen” comes from “sancio,” “to render inviolable,” the person of the bearer being looked upon as inviolable.
