[1] From the scholia to Aristophanes, Birds 123, where the genitive plural headword appears (city of the rugged ones); cf. n.3 below. "Rugged" was used to refer to several cities, including Ithaca (in Homer) and Athens (LSJ s.v. kranao/s) --- typically describing the city itself, and not its inhabitants as here. The reference was translated into a mythical Kranaos as progenitor of Attica, as in Aeschylus, Eumenides 1011, "Children of Kranaos".
[2] Quotation unidentifiable. (But Nonnus, Dionysiaca 22.20, 45.308 has the formula "the rocky stone [kranah\ pe/trh] swelled, disgorging wine".)
[3] Aristophanes, Birds 123; i.e. Athens.
