From the prologue of Francesca Caccini's *La Liberazione di Ruggiero*:> Meco venite, e con sonore voci, /> Numi dell'acque, reverite in pace, /> Chi vinse in guerra il Moscovita e'l Trace, /> E servirese i Tartari feroci.Is "servirese" an archaic conjugation of "servire"? (Passato remoto forse?) It doesn't make grammatical sense as an infinitive + reflexive pronoun, and furthermore it is set musically so that the 3rd syllable is stressed.
I am not familiar with this opera, however reading the extract you posted I would guess that SERVIRESE actually means "rese servi" - made slaves or enslaved.
