Midway along the journey of our life I woke to find myself in a dark wood, for I had wandered off from the straight path. How hard it is to tell what it was like, this wood of wilderness, savage and stubborn (the thought of it brings back all my old fears), a bitter place! Death could scarce be bitterer. But if I would show the good that came of it I must talk about things other than the good.

Love can move the Sun and the stars.

I made my own house be my gallows.

...ma gia volgena il mio disio e'l velle si come rota ch'igualmente e mossa, l'amor che move: i sole e l'altre stelle ...as a wheel turns smoothtly, free from jars, my will and my desire were turned by love, The love that moves the sun and the other stars.
