I'm still reading the Tales of 1001 Nights. I'm one-thirds of the way into the first volume, because I occasionally read one of the tales, rather than reading all of it in one go. And as you can tell by the pictures, these books are MASSIVE. The language can occasionally be a bit demanding to read, because it is pretty old and the phrasing is very elaborate. Like an over-enthusiastic dungeon master, there's a tendency in these tales for a lot of repetition and to go into a lot of unnecessary detail. If for example a character encounters a door, we are also told what kind of wood it is made of.
For example, I just read The Porter and the Three Ladies, where the tale goes into excessive detail regarding all the things one of the ladies buys at the market and has the Porter carry. There's also a ton of poetry in it, which can be a bit of a slog. Also, lots of stories within stories, which was once again the case with The Porter and the Three Ladies. On the other hand, also orgies and gruesome beheadings. This last tale even featured the fabled giant bird known as Rokh, which apparently is all white, as thick as 10 elephants, and as large as 20 camels. Who knew? We also learn what name each of the three ladies has given to their privates. Yes, you read that correctly.
According to wikipedia, the Porter and the Three Ladies is one of the few stories that is included in every known version of the Tales of 1001 Nights.
