From (ill-informed) glosses on Herodotus 1.103.1 (web address 1), where the present headword actually occurs as a prepositional phrase: Kyaxares was the first Median king who divided his Asian troops into regiments kata\ te/lea, literally "in accordance with (their) duties". (For Herodotus' liking for this phrase in his military descriptions see also 7.87, 7.211.3, 9.20, 9.22.1, 9.23.1, 9.33.1; and elsewhere cf. e.g. Arrian, Indica 18.12.)
