sestina

That it was used and admired by Dante and Petrarch, alone gives the sestina a royal precedence over all of the other forms.

The sestina, a very elaborate canzonet, was invented in Provence and borrowed by the Italians.

The common form of the sestina has six stanzas of six lines each, with a tercet at the end.

Naught else have I afforded you, madame, save very anciently a Sestina.

From Italy have come, besides the ottava rima and the sonnet, two other metrical forms, the sestina and the terza rima.
