Making Maps, Jarius Mercator, Tycho Brahe, John Davis

Making maps began early on in history. Ancient Greeks and people in the Bible believed the earth was round like a ball. Some early maps left out useful tools for sailing.

Jarius Mercator was born in 1512. He went to the same school in France as Vesalius. He changed his name from Cream to Mercator. He received credit for inventing the globe.

Tycho Brahe was an astronomer. He made two observations in the night sky. In 1572 he observed a supernova. In 1578 he observed the path of a comet.

John Davis was a sailor and explorer from England. He wanted to find a Northwest Passage. He invented the backstaff. It told you your location in the water by measuring the shadow of the sun.

  2. Nice job Liam! I think maps are really neat. Did you know that Captain Clark was the main map maker for the Lewis and Clark expedition? He did a really good job. Hope you get to learn more about maps soon.
