Humanity’s drive to explore our planet is one of the defining characteristics of our species. But exploration only works if you know where you are at any given time. Not so easy when you are out at sea with no visible landmarks and the stars above you are in constant motion. It turns out that the key to solving this puzzle is understanding that in order to know WHERE you are, you have to first know WHEN you are.

Imagine setting sail from Hawaii in a canoe. Your target is a small island thousands of kilometers away in the middle of the Pacific Ocean — a body of water that covers more than 160 million square kilometers. For thousands of years, Polynesian navigators managed voyages like this without the help of modern navigational aids. How did they do it? Alan Tamayose and Shantell De Silva explain.

How did the Great Explorers avoid getting lost at sea?
How did the Great Explorers avoid getting lost at sea?
The golden age of European ocean exploration – also known as the Age of Discovery – transformed international trade and commerce and laid the seeds for the world we live in today.
The 15th and 16th centuries, in particular, saw Portugal and Spain then Britain, France and Holland discover new trade routes and establish colonies throughout Africa, South Asia, and the Americas.
This was the period that produced some of the most famous explorers ever known – Columbus, Da Gama, Magellan.
Of course, all of this is common knowledge.
But how did they do it?

Antikythera Mechanism: The ancient 'computer' that simply shouldn't exist - BBC REEL
A hundred and twenty years ago, divers discovered a shipwreck off the island of Antikythera in Greece. What they found changed our understanding of human history.
The mysterious Antikythera Mechanism has captured the imagination of archaeologists, mathematicians, and scientists ever since, even inspiring the plot for Indiana Jones and the Dial of Destiny! Now, using the latest 3D x-ray and modelling technology, experts are unravelling the secrets of what this machine may have been capable of.

Sailing Across the World's Oceans with No Tech
Hawai'i—possibly the most remote island chain on the planet—was discovered hundreds of years ago by Polynesian voyagers wayfinding in canoes. These ancient explorers relied exclusively upon their knowledge of the stars, bird behavior and ocean swell patterns to find speckles of land. Today, the modern descendants of these explorers are circumnavigating the world's oceans using the same wayfinding techniques.

Australia Discovered 1400s. NOT 1600s. Proof Here #history #ancient #maps
The Piri Reis Map is a world map drawn by Ottoman admiral and cartographer Piri Reis in 1513. Here's an overview of the map:
1. **Creation:**
Piri Reis created the map in 1513 during the Ottoman Empire's reign. The map is part of a larger work known as the Kitab-ı Bahriye (Book of Navigation), a maritime atlas that included information about navigation, ports, and coastlines.
2. **Materials and Size:**
The map is drawn on a single piece of parchment, measuring approximately 90 by 65 cm. It is a fragmentary map, as a significant portion of it is missing.
3. **Geographical Coverage:**
The Piri Reis Map provides a depiction of the known world at the time. It includes coastlines of Europe, Africa, and parts of the Americas. Notably, it features a portion of the eastern coast of Sou...

Hawai'i—possibly the most remote island chain on the planet—was discovered hundreds of years ago by Polynesian voyagers wayfinding in canoes. These ancient explorers relied exclusively upon their knowledge of the stars, bird behavior and ocean swell patterns to find speckles of land. Today, the modern descendants of these explorers are circumnavigating the world's oceans using the same wayfinding techniques.

The Piri Reis Map is a world map drawn by Ottoman admiral and cartographer Piri Reis in 1513. Here's an overview of the map:
1. **Creation:**
Piri Reis created the map in 1513 during the Ottoman Empire's reign. The map is part of a larger work known as the Kitab-ı Bahriye (Book of Navigation), a maritime atlas that included information about navigation, ports, and coastlines.
2. **Materials and Size:**
The map is drawn on a single piece of parchment, measuring approximately 90 by 65 cm. It is a fragmentary map, as a significant portion of it is missing.
3. **Geographical Coverage:**
The Piri Reis Map provides a depiction of the known world at the time. It includes coastlines of Europe, Africa, and parts of the Americas. Notably, it features a portion of the eastern coast of South America and has been a subject of interest due to its potential representation of the northern coast of Antarctica.
4. **Sources and Annotations:**
Piri Reis compiled the map using various sources, including ancient maps, charts, and contemporary navigational information. He annotated the map with notes and explanations, offering insights into the origins of the geographical data.
5. **Unique Features:**
One of the map's unique features is its depiction of a southern landmass resembling South America, along with annotations suggesting the possibility of seafaring knowledge about parts of the continent. Some researchers have speculated about the map's portrayal of an ice-free Antarctica, which has generated debate and interest.
6. **Historical Significance:**
The Piri Reis Map is historically significant as it reflects the state of geographical knowledge in the early 16th century. It serves as a valuable artifact for understanding how cartographers of that era compiled and represented information from diverse sources.
7. **Discovery and Preservation:**
The map was discovered in 1929 in the Topkapi Palace in Istanbul. Although a significant portion of the map is missing, the surviving fragments have been carefully preserved and studied by historians, cartographers, and researchers.
8. **Controversies:**
The map has sparked controversies and debates, particularly regarding its depiction of regions like Antarctica. Some have suggested that the map indicates a level of geographical knowledge beyond what was conventionally accepted for the early 16th century.
In summary, the Piri Reis Map is a remarkable historical artifact that provides insights into the geographical knowledge and cartographic practices of the early 16th century Ottoman Empire.
Ancient maps are fascinating artifacts that offer glimpses into the perceptions, knowledge, and exploration of different civilizations throughout history. Here's an overview of various types of ancient maps:
1. **Ptolemaic Maps:**
- **Era:** Hellenistic (2nd century AD)
- **Notable Feature:** Based on the geocentric model, these maps were created by Claudius Ptolemy and showcased a world divided into latitude and longitude.
2. **Mappa Mundi:**
- **Era:** Medieval (500–1500 AD)
- **Notable Feature:** Elaborate, symbolic maps depicting a Christian worldview. They often included Jerusalem at the center and combined geographical, historical, and religious elements.
3. **Portolan Charts:**
- **Era:** Medieval to Renaissance (13th–17th centuries)
- **Notable Feature:** Navigational charts used by sailors, emphasizing coastlines, ports, and navigational directions. They played a crucial role in Mediterranean and later Atlantic navigation.
4. **Piri Reis Map:**
- **Era:** Ottoman Empire (16th century)
- **Notable Feature:** Drawn by Piri Reis, an Ottoman admiral, this map includes coastlines of Europe, Africa, and parts of the Americas. It's known for its potential depiction of the northern coast of Antarctica.
5. **Tabula Rogeriana:**
- **Era:** Islamic Golden Age (12th century)
- **Notable Feature:** Created by the Arab geographer Muhammad al-Idrisi, this map combined Islamic and classical geographical knowledge, providing a comprehensive view of the world.
6. **Hereford Mappa Mundi:**
- **Era:** Medieval (13th century)
- **Notable Feature:** A famous mappa mundi housed in Hereford Cathedral, England. It's richly detailed, combining geography, history, and biblical narratives.
7. **Ancient Chinese Maps:**
- **Era:** Ancient China
- **Notable Feature:** Chinese cartography dates back to ancient times, with maps often reflecting the political and cultural contexts of different dynasties.
Ancient maps not only served as navigational tools but also reflected cultural, religious, and scientific beliefs of their respective times. They continue to captivate modern audiences with their historical significance and artistic intricacies.
