[305] No doubt the remark of the scholia as to the superior merits of the form “ῥυσίπτολι” is right. The vulg. is evidently due to the analogy of “ἐρυσάρματες” 15.354, 16.370; but that is from “ϝερύω” to draw, a distinct verb from “ῥύομαι, ἐρύομαι” to protect (see on 1.216), which has “υ_” in the sigmatic forms with but few exceptions. “ῥυσίπολις” occurs in Septem 129. 306-7 are imitated by Virgil Aen. xi. 483 ff.
