Note 2526 — BOOK XXII. THE PROPERTIES OF PLANTS AND FRUITS.
John Bostock translation
As compounds of ἵππος, a “horse.” Hardouin, however, thinks that the names ἱπποφαὲς and ἱππόφαιστον have another origin, and that they are compounds of φάος, “lustre,”—from the brilliancy which they were said to impart to cloths—and ἵππος, in an augmentative sense, meaning “great lustre.”
