A little Islamic astrolabia of the eleventh century discovered in the vaults of a museum in Verona, Italy. One of the oldest examples ever discovered and one of the rare known in the world, the astronomical tool turns out to have been used through the other Muslim, Jewish and Christian people in Spain, North Africa and Italy Centurian premieres
Astrolabes was the “first smartphone in the world”, according to the University of Cambridge in a blog article that pronounces Discovery, a “laptop that can be only many uses. ” Showing a two -dimensional style of the universe, astrolabes made imaginable insinuate the position of the stars, calculate time and distances and expand the horoscopes.
The rare artifact, dating from the 11th century, was known as such through Dr. Federica Gigante at the University of Cambridge’s Faculty of History while hunting in a photo of the downloaded astrolabe with the recently downloaded symbol Astrolabe on the website of the Ministry of Museum Founding.
The museum had suspected it was false. “This is now the maximum vital object in his collection,” said Dr. Gigante, whose conclusions about “Verona Astrolabe” have been published today in Nonus magazine.
According to its inscriptions, the astrolabe turns out to come from Al-Andalus, the Muslim was reduced to the dominion of Spain in the eleventh century. However, Hebrew inscriptions have been added to the astrolaby, suggesting that “the object has left Spain or North Africa and circulated between the Jewish network of the Diaspora in Italy, where Arabic was not understood, and Hebrew used instead,” Dr. Gigante said.
The stars of “Verona Astrolabe” were placed in the position that the stars had at the end of the eleventh century. The Earth lights an axis that ranges for long periods, such as a rotation summit, returns to the same position each and every 25,920 years. This is called the precession of the equinoxes. This means that the northern star, lately Polaris, adjustments over time, as well as the positions of all stars in the sky of a given place. “The obvious positions of the stars on our heads are constantly changing, approximately one degree each and each of the 70 years,” said Dr. Gigante.
Therefore, it was imaginable to analyze the position of the stars in the astrolabio, allowing an approximate moment of the sky for which it was created. The stars gave the impression of being placed in the position where the stars were at the end of the eleventh century. – And it coincided with other astrolabes made in 1068 AD.
