The unglossed headword, in the nominative singular, occurs in the genitive singular in the quotation given.
[1] Damascius, Life of Isidore fr. 78 Zintzen (36 Asmus); cf. similar language in Photius' epitome of the Life of Isidore, Biblioteca 337b.22-24, although the current headword does not occur in Photius, or anywhere else outside the Suda. Compound nouns with a final element -foitwr (presumably related to the verb foita/w ('travel', 'visit')) are in general nearly non-existent; one other example, xqonofoi/tores ('earth-traveling', a poetic epithet for the Moirai), is attested in Joannes of Gaza, Carmina Anacreontea 5.5. The language of this fragment, and of the corresponding section of Photius' epitome, is heavily redolent of Plato's Phaedrus (see e.g. Phaedrus 247C on the "place beyond the sky" where the "winged ones" (sc. souls) graze)); it is possible that this rare and unusually-formed term was inspired by the Platonic hapax pterofu/tor(a) ('wing-sprouting') at Phaedrus 252B, which would have been indistinguishable in pronunciation from the present headword in late Greek.
