Books I tried to read, but gave up:
The Silmarillion by Tolkien
The City of God by Josephus
and many others I can’t remember
Hard books I made it all the way through by skimming and then claimed I read them. (I repent of doing this.)
Confessions by Augustine
Wars of the Jews by Josephus
LOL, it’s funny you repent re: the confessions. Btw, my very liberal Jewish friend told me years ago that Josephus was a notorious liar; but I don’t know if that is true.
“The Silmarillion by Tolkien”
Seems to be not such a good one, I think it got a few mentions in the comments on the linked site.
I listened to the Confessions on audiobook. I don’t know whether I would have made it through a hard copy. Some good parts and an amazingly modern perspective on life. Fun to read something read so long ago and feel like it was written last week.
