The headword -- evidently quoted from somewhere (perhaps the Septuagint, e.g. twice in Leviticus 9:20) -- is neuter nominative (and vocative and accusative) plural form of the substantive στέαρ (cf. LSJ s.v.), meaning either suet or spelt flour dough. The glosses (and the context of the quotation appended) suggest the latter.
Of uncertain botanical origin, but a common European staple grain beginning in the early Bronze Age (ca. 2000 BCE), spelt is an Old World wheat, Triticum spelta (Nesbitt, p. 37; omicron 224; sigma 1015; sigma 1014; zeta 43).
[1] The gloss is the neuter nominative (and vocative and accusative) plural form of the noun ἄλευρον , wheaten flour; cf. LSJ s.v. and alpha 1153. Same glosses in Photius and Lexica Segueriana 369.25; cf. Hesychius.
[2] Eunapius fr.52 FHG (4.37); cf. Blockley, pp. 70-1; alpha 2202; kappa 67. Blockley (ibid., p. 142) tentatively associates the passage with Zosimus 4.26.6, where count Julius communicates secretly with Constantinople senators. As Adler notes, MSS G and M contain παραπεπλασμένα , having been transformed. MS F also redacted the quotation: καὶ θεὶς ἐν πήρᾳ ἐπιθέντες καὶ , preferring the plural participle over ἐπιθείς . ἄλλους was deleted by Casaubon, who also followed MSS F and V in replacing ὁμοίους with ὁμοίως , similarly. Finally, Bernhardy deemed the passage corrupt.
