It was a vessel, sturdier than earlier vessels and adapted triangular sails that derived from the Arabs to help sail against the wind. Next, sailors used the astrolabe, which was a brass circle with carefully adjusted rings marked off in degrees. The instrument helped determine the ship’s location at sea, and by using the rings to sight the stars, the sea captain would be able to calculate the latitude of the ship. Three additional inventions that helped lead to the European exploration was the compass, map, and the printing press. The compass aids sailors by telling them what direction the ship was going, and was invented by the Chinese. The map was invented by the Greco-Egyptian astronomer Claudius Ptolemy, who wrote Geography around A.D. 150. This eight-volume book contained maps and the longitude and latitude of approximately 8,000 places. It also contained instruction for how to make maps. Maps provide information of what countries and places there are in the world, which sailors can use to help guide them the way. Last but not least, the printing press did it’s job of making plenty of maps, so that maps were quickly made, and provided for everyone at a price that was
