Each group retains its internal order; hence such periods are called “palinodic-antithetic”:— δι’ αἰῶνος μακροῦ πάνολβον· ἔνθεν πᾶσα βοᾷ χθών, “φυσιζόου γένος τόδε Ζηνός ἐστιν ἀληθῶς· τίς γὰρ ἂν κατέπαυσεν Ἥρας νόσους ἐπιβούλους;” Διὸς τόδ’ ἔργον καὶ τόδ’ ἂν γένος λέγων ἐξ Ἐπάφου κυρήσαις (Æsch., _Supplices_, 582 _sqq._). ⏑⁝⏗|⏗|–⏑|–⏑|⏗|–ꞈ‖ –˃|–⏑⏑|⏗|–ꞈ‖ ⏑⁝–⏑|–⏑|–⏑|⏗‖–⏑|–⏑⏑|⏗|–ꞈ‖ –⏑|–⏑⏑|–⏑|⏗‖–⏑|–⏑⏑|⏗|–ꞈ‖ ⏑⁝–⏑|–˃|–⏑|–⏑|–⏑|–ꞈ‖ –⏑⏑|–⏑|⏗|–ꞈ〛. ⎰ 6 ⎞ ⎛ ⎱ 4 ⎟ ⎞ ⎜ ⎰ 4 ⎞ ⎟ ⎟ ⎜ ⎛ ⎱ 4 ⎟ ⎞ ⎟ ⎟ ⎜ ⎝ ⎰ 4 ⎠ ⎟ ⎟ ⎟ ⎜ ⎱ 4 ⎠ ⎟ ⎟ ⎝ ⎰ 6 ⎠ ⎟ ⎱ 4 ⎠ (iv) Any of the three periods just described, the stichic, the palinodic, the antithetic (whether simple or palinodic-antithetic) may be “mesodic,” that is, it may be grouped round a central colon (the mesode), to which no colon corresponds, save of course the mesode of the other _strophe_.
