= Synagoge tau145, Photius tau231 Theodoridis (with some minor variation in orthography between th=|d' (Suda), th=| d' (Synagoge), and th= d' (Photius)). Apparently from commentary to Aristophanes fr. 402 Kassel-Austin, a fragment of his lost comedy Islands, as transmitted by Stobaeus 4.14.7: w)= mw=re, tau=ta pa/nt' e)n th=|d' e)/ni, "O fool, fool, all these things are possible/present in this." On the ambiguity of this phrase, see Labiano, esp. n. 10, who notes that the antecedent of the grammatically feminine pronoun tau/th| ('this') is uncertain; perhaps "peace" (as suggested by Kassel-Austin) or "land/estate". Also e)/ni (which in this context, with anastrophe of the accent = e)/nesti: (Smyth §175 n.2b)) is ambiguous; it could mean either 'are possible' or 'are present'. The former possibility is adopted in the present translation (and by Labiano), but the latter might be more compatible with the present gloss.
The subject of this implied verb is plural in the context (tau=ta); hence the plural translation both of the headword phrase and the gloss (where morphologically the expressed verb e)stin is singular).
Note also that, in the headword phrase, th=|d' appears to stand alone rather than as the object of the preposition e)n as it appears in the Aristophanes fragment. This leaves open the possibility that the lexicographer, in ignorance of the context, understands th=|de as adverbial (cf. tau 467 for this usage), but this possibility does not seem reflected in the gloss.
