Same (but longer) entry in ps.-Zonaras. Same lemma but no gloss, according to Adler, in the Ambrosian Lexicon.
The headword phrase is presumably quoted from somewhere, or generated by such a quotation, but its only precise parallel comes from the 11th century: Michael Psellos, Oratorio Minora 37.314. (Galen, though, writes of an 'ape's eye', and Gregory of Nazianzus' funeral oration for Basil of Caesarea includes the phrase piqh/keion ble/pei.)
On apes, see also pi 1576, pi 1577, pi 1578, pi 1579, pi 1580, pi 1581, pi 1582.
