For thousands of years, people have been fascinated with world exploration and discovering new places and cultures. Historically, one of the most efficient ways to navigate the world was traveling by sea. From the ancient Greeks to medieval Spanish kings, exploration was a major goal for governments because it offered the prospect of new commercial operations and trade routes. For example, Spanish ships could sail to China and bring back Chinese spices and silks (which were unavailable on mainland Europe) to sell to Spanish markets. Early explorers relied on a navigational system called “dead reckoning,” or calculating their position based on previous positions (like landmasses) and their estimated velocity and drift to make sure they did not veer off course; however, this method was an inexact science. As exploration became more important for Europe’s economic interests, advanced devices that made exploration easier and more exact were developed.
The “age of exploration” marked a new frontier for sea navigation. This epoch began in the 15th century when Portugal and Spain started to expand their commercial interests and trade routes across the oceans, resulting in the exchange of goods and sometimes even traditions. Sailors used new technologies to navigate across the world, including a device called the quadrant, a fan-shaped magnetic object that measured the altitude of stars, the moon, and the sun in order to determine the latitude of a ship. Another device was the compass, which used Earth’s magnetic poles to point navigators north, south, east, or west. Time-keeping devices, like hourglasses, were important in calculating how far and how fast a ship had sailed. Early navigators also used maps, although these were not always accurate and were often written during the course of the exploration. These maps were then improved upon with new explorations.
It was an exciting time to be an explorer. Governments would pay men to navigate ships across the open seas and discover new lands. One of the most famous explorers was Christopher Columbus, the Italian navigator who set out to find a more efficient route to India and instead stumbled upon what is now known as Central America and South America. At the time of his sailing, Columbus only had a few navigational instruments available to him, including the compass, an astrolabe (a device that predicted the location of stars and helped explorers determine their latitudinal or vertical position on a globe), a quadrant, and incomplete maps. Columbus’s incomplete knowledge of world geography and the imprecise navigational devices he brought with him caused him to inadvertently discover the Americas and all the rich natural resources available there.
You can imagine the difficulties explorers had with the available technologies during Columbus’s time when you think about Columbus’s experience. He meant to travel from Spain to India, which we now know would have required him to sail first west, then south, then north. Instead, Columbus traveled west and believed he had reached the farthest place from Spain, the complete opposite side of the world: India. On the one hand, the tools’ inaccuracies made exploration by sea inconsistent and unpredictable; on the other, explorers at the time had limited knowledge of the world’s geography, which also hindered exploration of unknown territory. These issues, along with the financial risks involved, made it difficult for some governments and kings to agree to fund explorations during which their navigators could become irretrievably lost.
As time went on, more European countries began to explore the world. In the late 17th century, Great Britain joined the navigational tool race, developing modern tools such as the sextant and the chronometer, which replaced tools used by the earliest explorers. The sextant was used to measure the angles between the horizon and celestial objects in order to determine the ship’s latitude. Longitude was nearly impossible to calculate until the invention of the chronometer, an accurate timekeeping device. These modern inventions arrived after much of the world had already been explored, but allowed ship captains to cut down the length of time they were at sea, and improved accuracy in route planning.

The age of exploration marked a significant period in history, where nations sought to expand their interests and trade routes by venturing into the unknown. For centuries, sea travel served as the most efficient means for world exploration, offering the potential for new commercial operations and lucrative trade opportunities. However, early explorers faced numerous challenges, relying on rudimentary navigational methods such as dead reckoning, which limited their accuracy and precision.
During the 15th century, Portugal and Spain led the way in exploration, setting sail across oceans to establish new trading routes and exchange goods. To navigate the vast seas, sailors utilized emerging technologies, such as the quadrant, a magnetic device that measured celestial altitudes to determine latitude, and the compass, which relied on Earth's magnetic poles to point navigators in the right direction. Time-keeping devices, like hourglasses, were crucial for calculating distance and speed. Additionally, early navigators used maps, although their accuracy varied and improved over time with new discoveries.
The era of exploration attracted daring individuals who sought adventure and discovery. Christopher Columbus, an Italian navigator, is one of the most renowned explorers of this period. Although his original intention was to find a more efficient route to India, he inadvertently stumbled upon Central and South America. Armed with limited navigational instruments and incomplete maps, Columbus was unaware of the existence of the Americas. This lack of knowledge, coupled with the imprecise tools at his disposal, led to his unexpected discovery of an entirely new land and its abundant resources.
Columbus's experience highlights the difficulties faced by explorers during this era. The inaccuracies of the available navigation tools made sea exploration inconsistent and unpredictable. Furthermore, explorers had limited knowledge of the world's geography, hindering their ability to navigate unknown territories effectively. These factors, combined with the financial risks involved, made it challenging for governments and kings to fund explorations, fearing the potential loss of their navigators.
As time progressed, more European nations joined the quest for exploration. In the late 17th century, Great Britain emerged as a prominent player, leading the way in developing modern navigational tools such as the sextant and the chronometer. The sextant allowed sailors to measure angles between the horizon and celestial objects, providing a means to determine latitude accurately. Calculating longitude, which had been a formidable challenge, became possible with the invention of the chronometer, a precise timekeeping device. While these advancements came after much of the world had already been explored, they significantly improved navigation accuracy, reducing the time spent at sea and enhancing route planning.
In conclusion, the age of exploration catapulted humanity into uncharted territories, driven by the pursuit of new trade routes and discovering unknown lands. Sea travel served as the primary means for exploration, despite the limitations of early navigational tools and incomplete knowledge of world geography. Nevertheless, brave explorers like Christopher Columbus paved the way for future advancements, which ultimately revolutionized navigation and opened new doors for global connectivity. The age of exploration stands as a testament to human curiosity, bravery, and the thirst for knowledge that has propelled our world forward.
