Important Inventions

History 4 – Lessons 56 – 60 Essay

This week I learned about four inventions: the Trebuchet, Distilled Spirits, the Vertical Windmill, and the Stern-Mounted-Ruder.

The first invention is the Trebuchet. The Trebuchet is a bigger catapult and instead of originating from the crossbow it originated from the sling. Its impact was being able to break walls easily, and defend castle walls. They also could be fired at targets that couldn’t have enough reach to hit them with crossbows. 

The second invention was Distilled Spirits. Distilled Spirits are a strong type of alcohol like rum that could make you feel good if you don’t drink it too much. It’s impact on history was  that it was used as a treatment for the plague “Black Death.”   

The third invention is the Vertical Windmill. The Vertical windmill is a tall building with four sails. Its impact on history was that it produced electricity and made bread for the people who lived there.

The last invention was the Stern-Mounted-Ruder. It was a wooden paddle that attached to the under side of a boat and when you turn wheel it turns the rudder. Its impact on history was that you can steer the boat easily, which meant people could transfer goods to other continents, cities, countries, or even states! These inventions changed the world.
