This is confirmed by Sophocles, who in his play *Triptolemus* represents Demeter as telling Triptolemus how large a tract of land he would have to travel over while sowing it with the seeds she had given him. (Dionysius of Halicarnassus, Roman Antiquities, Book I, Chapter 12, in the Loeb Classical Library edition, translated by Earnest Cary.)
