So Glosses on Herodotus 1.37 (epsilon6), referring to the dative plural of this neuter noun in Herodotus. 1.133.2 (web address 1). The passage is quoted twice in Athenaeus, Deipnosophists: 4.144A and 14.641A [4.23 and 14.47 Kaibel]. In the latter context Athenaeus also preserves several quotations from Old Attic Comedy which use the word (Archippus, Philyllius); and other lexica -- Pollux 6.79; Hesychius epsilon5390; Photius, Lexicon s.v. tragh/mata (sic) -- give a generalized citation of Aristophanes on the subject. (The source behind Hesychius epsilon5390 is unstated.)
