His investigations into the usages and customs of his native Attica were embodied in an Atthis, in seventeen books, a history of Athens from the earliest times to 262 B.C. Considerable fragments are preserved in the lexicographers, scholiasts, Athenaeus, and elsewhere.
Their writings were much used by historians, as well as by the scholiasts and grammarians.
Among scholiasts may be mentioned the Scholiasta Bobiensis who is assigned to the 5th century, and a pseudo-Asconius, who wrote notes upon the Verrines dealing with points of grammar and rhetoric.
Numerous quotations and fragments still exist, chiefly in the Homeric scholiasts and Stephanus of Byzantium.
