That was a reaction engine, something like a steam rocket confined to rotate in a circle, and not a positive-displacement engine: https://en.wikipedia.org/wiki/Aeolipile

They couldn't use it as anything else than a toy. The reason they couldn't because they didn't have the metallurgy and the machining to create pistons, valves, etc.

IMHO they definitely had the processes to basically add a PTO to one, but it was probably dismissed as impractical.
