Translation - Poi s'ascose . . . - Line 427

Italian - From Dante's Purgatorio, Canto XXVI 148
Poi s'ascose nel foco che gli affina.
Then he hid himself in the fire that purifies them.
More fully:

«Ara vos prec, per aquella valor
que vos guida al som de l'escalina,
sovenha vos a temps de ma dolor!».
Poi s'ascose nel foco che li affina.

'And so I pray you, by that virtue
which guides you to the top of the stair,
be reminded in time of my pain.'
Then he hid himself in the fire that purifies them.

Although most of Dante's The Divine Comedy is written in Italian the quoted part of this extract is written in Provencal. The last line of the extract is Italian.
