Technological Advancements in the 15th Century
By J. Titus
Technological developments Advancement in ship designs Development in navigational
instruments Invention of the printing press Weapons
Caravel- Advanced ship design of the 15th Century
The Caravel Developed in the 15th century on the
Atlantic coast of Spain and Portugal. Was based on the design of the vessels used by the Arabs (Muslims). It had two of three masts with triangular (lateen) sails. As time went by it increased in size with a square sail on the foremast and lateen sails on the others.
Caravel The square and triangular shape
combination of the sails gave the ship the ability to sail close to the wind, this was essential if successful voyages were to be made in regions where the wind pattern was unknown. Sailors could now handle the ship better at sea
The Stern-post Rudder
The stern-post-rudder Helped sailors to maintain a steadier
course.
The Astrolabe
The Astrolabe
The Astrolabe Was used to tell the location of the ship
at seas using lines of latitudes. The astrolabe was used to observe either the altitude of the sun at midday or the altitude of the polar star at night.
The Astrolabe It consisted of little more than a
graduated metal circle with a revolving pointer and a turning board in the centre.
The Quadrant
The Quadrant This was a graduated quarter circle of
wood, with sighting holes mounted on one edge, and a plumb-bob hanging from the apex. This was used to determine the location of the ship at sea.
Invention of printing
Invention of Printing With the invention of the printing press
information about geography, science, literature and news could be copied and passed on easily in the form of books, charts and maps.
Weapons The earliest guns were probably
produced by the Arabs in North Africa about AD 1250. These were soon copied in Europe and by the 15th century gunpowder and guns of all description s were widely used. Caravels soon carried cannons.
