an Nome. There are five parts of it: angkrousis, ampeira, katakeleusmos, iambi and dactyli, and syringes. Now the melody was composed by Timosthenes, the admiral of the second Ptolemy, who also compiled The Harbours, a work in ten books;If the text of this sentence is correct, Strabo must be referring to the melody played as the Pythian Nome in his own time or in that of some authority whom he is quoting, earlier compositions perhaps having been superseded by that of Timosthenes (fl. about 270 B.C.). But since the invention of the Pythian Nome has been ascribed to Sacadas (Pollux 4.77), who was victorious with the flute at the Pythian Games about three hundred years before the time of Timosthenes (Paus. 6.14.9, 10.7.4), Guhrauer (Jahrb. für Class. Philol., Suppl. 8, 1875-1876, pp. 311—351 makes a strong argument for a lacuna in the Greek text, and for making Strabo say that the melody was composed by Sacadas and later merely described by Timosthenes in one of his numerous works.
