Upon the journey of my life midway,
I found myself within a darkling wood,
Where from the straight path I had gone astray.

[Nel mezzo del cammin di nostra vita,
mi ritrovai per una selva oscura,
ché la diritta via era smarrita.]

Dante Alighieri (1265-1321) Italian poet
The Divine Comedy [Divina Commedia], Book 1 “Inferno,” Canto 1, l. 1ff (1.1-3) (1320) [tr. Minchin (1885)]
