A boy, Urian, shows us the sights of Ancient Sumer, located in modern-day Iran, on his way to school.

We find out about many of the inventions developed at the time, as well as the careful urban planning that went into the city of Uruk.

He explains their writing system, using a reed to scratch marks on wax tablets, and the impact this had on life.

He claims teachers are very tough, but agrees he is lucky to go to school, as most people can't read or write.

We discover some of the reasons why the Sumer eventually died out.
