(Δῆμ́ος). If the reading in Athen. aeus (xiv. p. 660) is correct, Demus was the auquoted thor of an Atthis, of which the first book is there quoted. But as Demus is not mentioned anywhere else, Casaubon proposed to change the name into Κλειτόδημος, who is well known to have written an Atthis. If the name Demus is wrong, it would be safer to substitute Δήμων than Κλειτόδημος, as Demon wrote an Atthis, which consisted of at least four books.
