Renaissance Inventions

There are many things that we take for granted that were invented in the Renaissance era. Many of these inventions we use without thinking who created it and how it came about. Some of these inventions include the clock, gunpowder and artillery, eye glasses and spectacles, the printing press, the flush toilet, the microscope, the telescope, and the match.
In the beginning of the Renaissance time period, we can see the first portable clocks developed in Florenece, Italy, in 1410 by Filippo Brunelleschi, a famous architect. Before this time, mechanical clocks were large, fixed devices. The spring- driven clock made it possible to carry the time around with you.
Gunpowder was invented around 1040. Although hard to believe, rockets were launched as fireworks and weapons in China in the early 1230's. This led the way to William Congreve developing rockets to use during wars. Launching tubes were developed by this engineer to improve their accuracy. Also coming from the invention of gunpowder was the gun and other projectile-firing artillery. These new inventions greatly affected how war was fought. War used to be hand-to-hand combat with specific implied rules of chivalry. With these new, more powerful weapons, there were a higher number of casualties and more serious wounds. In turn this also affected the world of medicine.
Another important advance in science was the invention of convex and concave lenses. This led to the invention of bifocals which could correct people's eyesight. Also, lenses led to the inventions of telescopes and microscopes, which led to hundreds upon thousands of advances in multiple fields of science.
A big development in writing and literature was the invention of the printing press. Invented in 1436 by a 39 year old German man named Johann Gutenberg, the printing press was a great improvement over hand-copying. Before the development of this time-saving and economical machine, monks had to hand copy everything. This time-consuming process made books and scripts extremely hard to come by, and astronomically expensive. Gutenberg used his printing press to put ink on hundreds of individual letters that could be combined in numerous ways to create an entire page of text. After this stage was completed, as many copies as desired could be made. However, to print a different page, the individual letters had to be completely rearranged. This great invention helped Gutenberg reach his greatest achievement of the first mass-production of the Bible, which he published in 1456 in Mainz, Germany.
An important invention used by all, was the flush toilet. It was invented by Sir John Harington. Harington invented a valve that when pulled would release water from a water closet. Sir John recommended flushing the toilet once or twice a day, although with our modern technology, we know that is probably not sufficient. (Robin Hood didn’t name the toilet either.)
Fire was difficult to create until Robert Boyle invented the match in 1680. Although fire could be made by rubbing sticks together or by striking flint to steel, this was a time consuming process. Boyle discovered that when phosphorus and sulfur were rubbed together, they would burst into flame. Boyle knew that this was not because of friction, but because of chemical nature of these two substances. Boyle's matches were not safe because sometimes they accidentally went up in flames while in a pocket. With some improvements and a little fine tuning, this invention led to your modern safety match many years later.
