Who?

by AxelFlameTarshil

This is a little thing that I wrote and it makes my English teacher want me to write more of it. I don't know what they call these but I would like to know please. Send me an email if you know what these are called. Thanks!

A red flower in a field of black,
A lion sleeping still, tall and brave,
Ruling people her happy slaves,
Giving help to those who need it.
