For the primary headword see already pi 1233.
[1] = Aelius Dionysius pi41, Photius pi804 Theodoridis, and cf. the scholia to Thucydides 4.87.1. Thucydides uses the word periwph/ only in that passage, and does so in the idiosyncratic sense indicated here. He uses the masculine nominative plurals pi/sunoi three times (2.89.6, 5.14.3, 6.2.6) and pu/steis once (1.5.2). The lexicographers' point seems to be that Thucydides could have chosen more everyday synonyms for all these; the latter two, in particular, are rarely used in prose. The adjective applied to them here, glwttw/dh, is elsewhere only applied to people, and in the pejorative sense of loudmouthed/talkative/verbose (most of its attestations are in commentary to a number of instances of it in the Septuagint, e.g. Proverbs 21:19, Ecclesiastes 8:3, Psalm 139:12); however, that sense is inappropriate here, and 'recondite' is Stephen Usher's translation of the term glwsshmatika/ in the passage of Dionysius of Halicarnassus' Second Letter to Ammaeus (3) where he anticipates the lexicographers' point and gives the present headword as one of four examples.
[2] Agathias, Histories 1.21.4 (37.23 Keydell), on the Byzantine general Narses (cf. nu 42) moments before the Battle of Ariminum (modern-day Rimini, cf. alpha 3884) in 553 CE; cf. Frendo (29). The word translated here as 'viewpoint' (peri/skeyis) is the same word translated as 'consideration' in the previous paragraph, where the term is used in an abstract sense and explicitly not in reference to a physical location. Clearly in the Agathias quotation the term refers concretely to an actual viewing-point, but this distinction seems to have escaped whoever added this quotation. On the Gothic War (535-554) battle itself, see also alpha 202, epsilon 3550, and pi 110.
