I came into possession of an old Bible some time ago, a compilation of the Old and New Testaments. I'm not typically an avid reader of religious texts, but I find the writing style, especially the old font, fascinating. Occasionally, I delve into the book, although it takes about 3-4 times longer than usual as I often have to look up certain letters and words.

I don't read it very often, as you can see, since it has aged over the years.

What is the oldest book you own, and what is it about?
