[137] ὀλοοίτροχος recurs in an oracle in Herod.v. 92. 2, and Theokr. 22. 49; and in the form “ὁλοίτροχος”, Herod.viii. 52, Xen. Anab. iv. 2. 3.The word is no doubt for “Ϝολοϝ-οίτροχος”, from “Ϝελ-υ”, to roll, Lat. vol-v-. The -“οι”-, however, is not explained; we can hardly compare “ὁδοιπόρος”, where it is clearly the locative termination (H. G. § 124 f). Perhaps we ought to prefer the variant “ὀλοότροχος”. The scholia generally refer the word to “ὀλοός”, as though = running destructively.
