[2] Aristophanes fr. 506 Kock, now 520 Kassel-Austin. The Suda's quotation follows a scholion to Aristophanes, Acharnians 640 (web address 1), whereas the received fragment, from the comedy Fry-Cooks (Henderson, p. 355), reads ta\ lipara\ ka/ptwn: by bolting the oily things. See also alpha 1244, theta 433.
