The unglossed headword, the noun e)kbiasth/s, is attested only here and in the entry of ps.-Zonaras for the accusative plural grammatoeisagwgei=s, which corresponds with e)kbiasta/s and paideuta/s, i.e. teachers (of the forceful, insistent kind). It is closely connected with the concept of education, in its broadest sense, as shown in a reference by Theodorus Studites (Letters 384.52): e)kbiastw=s, h)/toi sumbouleutikw=s, "that is to say advisory".

In his footnote to this passage, however, Tartaglia identifies (301, n. 82) this exactor of justice as Gregory of Nyssa (c.335-c.394), Basil's brother (cf. next note). At Against Severus 649-650 the Pisidian notes *)/hdh de\ loipo\n kai\ to\ phgai=on sto/ma to\ *grhgori/ou tou\s lo/gous a)nabru/ei ("But, for the rest, Gregory's well-springing mouth gushes forth with his arguments"); the Nyssen was indeed renowned for his eloquence; cf. gamma 451.
