This book in the Horrible Histories series centres around the Romans. Obviously there are a lot weird things to tell about the Romans. Like some of the emperors who had lost their minds.
Like Caligula, who loved his horse so bad, he promoted him to consul, and had a palace built for him, so he could get guests over.
Or Elagabalus' fine dining diners.
Or how about Nero? The list is long...
This book (for children, but also nice for people who are a bit older than that) shares again some interesting facts with us concerning Romans and everyday life in the Roman Empire. Nice drawings accompany the text.
