Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...

John II Of France
John II (french: Jean II; 26 April 1319 – 8 April 1364), called John the Good (French: ''Jean le Bon''), was King of France from 1350 until his death in 1364. When he came to power, France faced several disasters: the Black Death, which killed nearly 40% of its population; popular revolts known as ''Jacqueries''; free companies (''Grandes Compagnies'') of routiers who plundered the country; and English aggression that resulted in catastrophic military losses, including the Battle of Poitiers of 1356, in which John was captured. While John was a prisoner in London, his son Charles became regent and faced several rebellions, which he overcame. To liberate his father, he concluded the Treaty of Brétigny (1360), by which France lost many territories and paid an enormous ransom. In an exchange of hostages, which included his second son Louis, Duke of Anjou, John was released from captivity to raise funds for his ransom. Upon his return to France, he created the franc to stab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
