A long, long time ago, when people were still learning how to read and write, there was a special box called a sarcophagus. This box was made out of stone and it was very fancy!
One day, someone named Tabnit was very important, and when he passed away, they put his body inside this special box. On the box, they wrote lots of words in a language that most people didn't know how to read.
Many, many years went by, and the special box was moved to a big museum where people could come and see it. Some very smart people who could read the words on the box studied it and learned about Tabnit and what his life was like a very long time ago.
Now, lots and lots of people visit the box, called the Tabnit sarcophagus, and they marvel at how beautiful it is and how much it can teach us about history.
