[ WP ] Explain a piece of modern technology to a person from around 100-500 CE .

`` So, what is this?'' He pointed at my Kindle. 
 
 `` It's a library.'' Simple enough, I suppose. 
 
 `` How does it work?'' 
 
 I looked over at Steve, who was still smoldering from his execution. The less science, the better, I reminded myself. 
 
 `` Well, the holy man Jeff Bezos prayed to God for a way to enlighten mankind, and God delivered millions of these Kindles. They're named that because, like a light in the darkness, Kindles illuminate mankind through a library that would otherwise be the size of a castle.'' 
 
 The man blinked at me. I continued. 
 
 `` They're a gift from God to all of His children.'' 
 
 `` But only the priests can read.'' 
 
 The cover of *The God Delusion* still shone on the screen. 
 
 *Thank God, * I thought.
