[1] = Eudemus 170.15 Niese, Synagoge, Photius pi36 Theodoridis, and cf. Hesychius pi94; probably all deriving from commentary on Aristophanes, Clouds 260 and 262 (see n. 2 below). See also kappa 2389.
[2] Aristophanes, Clouds 260 (web address 1), with comments from the scholia. The commentator here seems to have misinterpreted the metaphorical meaning of the headword based on its resemblance to another word, pai/palon, used of rocky places. In the context Socrates is speaking to Strepsiades and promising to make him a subtle speaker; hence the reference is to the clear sound of the castanet and the extreme fineness and subtlety of 'flour'. Other commentators and scholiasts either infer or report from other sources that paipa/lh is the finest of the flours, the implication being nearly the opposite to the interpretation of this commentator. The etymological relationship between paipa/lh and pai/palon -- if any -- is unclear. For other entries dealing with words related to one or both, see pi 887 through pi 890.
