Late 15th Century
The
Motivation For the Exploration Of The Coastline Of Africa:
The fall of
Byzantine Constantinople to the Turks in 1453 along with the expulsion
of the Moslems from the Iberian Peninsular in 1492 had raised religious tensions
in the Mediterranean and Middle East to an unprecedented level. The
caravans traveling along the western sections of the
silk, spice and incense routes of were
often subjected to punitive levies from the Moslem overlords, and rebel
bandits would plunder and murder at will. The high risks being
encountered in delivering the goods to the European market place forced
prices to levels that were considered exorbitant and unaffordable. Many
of the merchant states of the Mediterranean were facing economic crisis.
The Quest for an Alternative Route to the East:
For centuries the Europeans had listened to the
stories about brave seafarers of ancient times having sailed south along
the coastline of Africa and rounding the most southern tip of the
continent. It was generally agreed that this could be the alternative
trade route to the riches of the East, but how to get there, and in what
type of ship, and how to return safely all presented problems that
stretched the limits of imaginations and science of the day.
Henry The Navigator:
One bold innovator was Prince Henry (1394-1460) the third
son of King John 1 (1357- 1433) of Portugal. Henry was fascinated with
the challenge of sea travel. He made his residence at Sagres near Cape
Saint Vincent, and there he built an observatory and established
Europe's first school for navigators.
The Caravel, A Revolution In Ship Design:
Prince Henry
also helped to develop a new class of ship that became know as the
caravel (Portuguese - Caravel, from the Greek - Karabos, or
Arabic - Qarib). They were small vessels in relationship to the lumbering
galleys that had plied the Mediterranean over 2 millenia. Approximately
16m in length and having two or three short masts that carried lateen
sails. They looked more like an Arab Dhow than a product of Western
Europe, but the craft were seaworthy and were capable of sailing close
to the wind. It was in these fast, robust little ships that the
Portuguese began to explore the West Coast of Africa, and by 1446 they
had reached as far South as the Gambia River.
The Padroes (Stone Crosses):
The discoveries being made along the West-African coast were the most impressive of the times
and Pope Sixtus V proclaimed Prince Henry's nephew King John II
(1455-1495) as being the "Lord of all of the African Possessions". The
king ordered that (Padroes) commemorative pillars of limestone depicting
the coat of arms of Portugal and surmounted with a Cross to be carved.
These were to be erected at prominent places to serve as landmarks and
also to proclaim sovereignty for Christianity and Portugal. The Padroes
were about 3,5m in height and weighed 360kg
