Aeolic poetry, the most famous example of which being the works of Sappho, mostly uses four classical meters known as the Aeolics, which are: Glyconic (the most basic form of Aeolic line), hendecasyllabic verse, Sapphic stanza and Alcaic stanza (the latter two so named after Sappho and Alcaeus respectively).
Both were completed by early in 1516, and are often cited together with the Sophonisba (1515) of Gian Giorgio Trissino as being the first classical tragedies in the vernacular language that would later be called Italian; they are also the earliest works to be written in blank (unrhymed) hendecasyllables.
The double mention of "papé" together with "Satan" (here interpreted as the fallen angel Satan) and the break (the comma) in the hendecasyllable, gives it a tone of a prayer or an invocation to Satan (although there is no verb traceable).
Both were completed by early 1516 and are based on classical Greek models, Rosmunda on the Hecuba of Euripides, and Oreste on the Iphigenia in Tauris of the same author; like Sophonisba, they are in Italian and in blank (unrhymed) hendecasyllables.
