Sky Explorer from Toledo
Imagine a world without accurate maps or reliable compasses. In the 11th century, in the city of Toledo, which was a center of cultural fusion between Islam, Christianity, and Judaism in Al-Andalus (Islamic Spain), emerged a man who changed the way humans read the stars. His name was Abu Ishaq Ibrahim ibn Yahya al-Zarqali al-Tujibi, more commonly known as Al-Zarqali. In Latin tradition, he was called Arzachel, meaning 'engraver'โa fitting title for a skilled astronomical instrument maker.
From Metal Engravings to Sky Engravings
Al-Zarqali was born in 1029 AD in Toledo, when the city was one of the most important centers of knowledge in the Islamic world. He was not only an astronomer but also a skilled instrument maker. At that time, the astrolabe was already an essential navigational and star-measuring tool. However, traditional astrolabes were flat and could only be used at a specific latitude. Al-Zarqali saw this weakness and began creating something revolutionary.
Saphaea: The First Spherical Astrolabe in the World
Al-Zarqali's greatest creation was Saphaea, the first spherical astrolabe in the world. Unlike flat astrolabes, Saphaea was spherical and could be used at any latitude without requiring additional plates. This device allowed sailors and astronomers to measure the height of stars, determine prayer times, and establish the direction of the qibla more accurately. This design was so advanced that it was widely used by European sailors until the 16th century, including in the voyages that discovered new worlds.
An Instrument That Guided the Seas
The excellence of Saphaea was not only in its innovative shape but also in its accuracy of use. Al-Zarqali also produced an astronomical table known as the "Toledan Tables," which became a primary reference for astronomers in Europe for centuries. These tables contain data on the movement of the sun, moon, and planets, which helped in weather forecasting, determining seasons, and navigation. His work was translated into Latin and Spanish, becoming an important source of knowledge for scientists such as Copernicus and Kepler.
Legacy That Touches the Moon
Al-Zarqali died in 1100 AD in Cordoba, but his legacy continues. The Arzachel crater on the moon is named after him, honoring his contributions to the field of astronomy. He also left behind a tradition of precise and innovative astronomical instrument making, continued by generations of Islamic scientists in Al-Andalus. His work proves that the Islamic civilization not only preserved Greek knowledge but also developed and created new technologies that changed the world.
Conclusion: From Al-Andalus to the Whole World
The story of Al-Zarqali is a brilliant example of how a scientist from Al-Andalus was able to create an instrument that became the backbone of global navigation. In a challenging world, he not only observed the sky but also engraved it in the form of metal and spheres. Saphaea is not just a tool; it is a symbol of the glory of the Islamic civilization that dared to dream and create. Today, when we look at the stars in the night sky, remember that a man from Toledo once taught us how to conquer the seas and understand the universe.

Al-Zarqali: The Creator of the Spherical Astrolabe from Al-Andalus Who Changed World Navigation. This article recounts the life and contributions of Al-Zarqali, an astronomer and instrument maker from Al-Andalus in the 11th century. He is famous for creating the first spherical astrolabe (Saphaea) in the world, which was later used by European sailors until the 16th century. His work became a bridge between Islamic and European civilizations, leaving a lasting legacy in the history of science.. Sky Explorer from Toledo
