57. καὶ ὡς ἐπῆλθεν ἡ ἑορτή, Ἱππίας μὲν ἔξω ἐν τῷ Κεραμεικῷ καλουμένῳ μετὰ τῶν δορυφόρων διεκόσμει ὡς ἕκαστα ἐχρῆν τῆς πομπῆς προϊέναι...
In the above quote, ἕκαστα is listed as a singular, feminine, nominative doric aeolic adjective. At least, that is what has the most votes on Perseus Project.
My best guess had been that it was a plural neuter adjective, since I am not familiar with doric aeolic spellings. But I have never thought of "each" as being plural. What would the plural be? "Every"?
Can someone help me out with this? I cannot find any indication that Thucydides wrote in a doric aeolic dialect. If he does, it was very shabby of the text I was using not to give me help with that word.
