Schema Pindarĭcum（σχῆμα Πινδαρικόν) or Schema Boeotĭcum (σχῆμα Βοιωτικόν). A name given to the use of a masculine or feminine subject in the plural joined with a verb in the singular —e. g. in Pindar ( Olymp. xi.[x.]):
ὕμνοι ὑστέρων ἀρχαὶ λόγων τέλλεται. Other instances (the construction is a rare one) are found in Herod.vi. 86(in an oracle); Hymn. in Cer. 279; Pyth. x. 71; Hesiod, Theog. 321; and with the noun in the dual number in Il. xxiii. 477.In Attic writers the construction is usually limited to ἔστι and ἦν placed at the beginning of the sentence, so that the subject follows the verb and the expression is somewhat impersonal in its form, as in the French Il est des hommes, etc. Cf. Soph. Trach. 520; Eurip. Ion, 1146; Plato, Euthyd. p. 302 C; and for further instances, see Jelf, Greek Grammar, 386.
