[sc. An epithet of] Pan; since he seems to have the hooves of a goat; hence he is also called "goat-feeding" and "goat-footed." Or because he has horns. Or in having a horny step; for he is observed to have the lower extremities of a goat, so that he's called "horn-footed" from his feet. Or as one who walks into the horns [i.e. peaks] of the mountains. Or as one who walks on the peaks.[1] 'Playing his reed-pipe': because the ancients used reed rather than horn [for pipes]. For they knew horn[-pipes] but retained the name [reed-pipes] in conformity with the older usage; as we even now say gut-strings from sinew, since in early times they were made of gut.
And [there is] a saying: 'give [me] horn-tipped bows'.[2]
