Dante Alighieri 
The Divine Comedy: Paradise [EPUB ebook] 

The glory of Him who moves everything penetrates through the universe, and shines in one part more and in another less. In the heaven that receives most of its light I have been, and have seen things which he who descends from thereabove neither knows how nor is able to recount; because, drawing near to its own desire, our understanding enters so deep, that the memory cannot follow. Truly whatever of the Holy Realm I could treasure up in my mind shall now be the theme of my song.
