ῥοδανός

ή, όν
A. wavering, flickering, παρὰ ῥοδανὸν δονακῆα Il. 18.576:—this is the reading of most codd., but ancient critics differed as to the form; Zenod. gave διὰ ῥαδαλόν (which he derived from κραδαλόν); the reading of Aristoph. and Aristarch. is uncertain, perh. παρὰ ῥαδινόν, v. Sch. ad loc.; cf. also ῥαδινός (Apollon. Lex., who reads ῥαδινόν, absurdly interprets as λεπτόν, οἱονεὶ ῥαδονόν, παρὰ τὸ ῥᾳδίως δονεῖδθαι).
