Gerbert D'Aurillac
Pope Sylvester II (; – 12 May 1003), originally known as Gerbert of Aurillac, was a scholar and teacher who served as the bishop of Rome and ruled the Papal States from 999 to his death. He endorsed and promoted study of Moorish and Greco-Roman arithmetic, mathematics and astronomy, reintroducing to Western Christendom the abacus, armillary sphere, and water organ, which had been lost to Latin Europe since the fall of the Western Roman Empire. He is said to be the first in Christian Europe (outside of Al-Andalus) to introduce the decimal numeral system using the Hindu-Arabic numeral system. Early life Gerbert was born about 946, or at any rate between 945 and 950. His exact birthplace is unknown, but it must have been in what was then the Duchy of Aquitaine, part of the Kingdom of France. More precise proposals include the town of Belliac, near the present-day commune of Saint-Simon, Cantal, or Aurillac. Another speculated location is the province of Auvergne. Gerbert's ...

Armillary Sphere
An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (on the celestial sphere), consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features, such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere whose principal purpose is to map the constellations. It was invented separately, in ancient China possibly as early as the 4th century BC and ancient Greece during the 3rd century BC, with later uses in the Islamic world and Medieval Europe. With the Earth as center, an armillary sphere is known as '' Ptolemaic''. With the Sun as center, it is known as '' Copernican''. The flag of Portugal features an armillary sphere. The armillary sphere is also featured in Portuguese heraldry, associated with the Portuguese discoveries during the Age of Exploration. Manuel I of Po ...

Borrell II (died 993) was the count of Barcelona, Girona and Ausona from 945 and count of Urgell from 948. Borrell was first seen acting as count during the reign of his father Sunyer II in 945 at the consecration of the nunnery church of Sant Pere de les Puelles in Barcelona. In 947, Sunyer retired to monastic life and ceded the government of his realms jointly to his sons Borrell and Miro I. In 948, Borrell inherited Urgell from his uncle Sunifred II. Sunyer died in 950, and Miro died in 966, leaving Borrell sole ruler of more than half of Old Catalonia, a status which led outsiders and flatterers to refer to him as ''dux Gothiae'', "Duke of Gothia".
