Ludwig van Beethoven was a German composer, pianist, and conductor, one of the most famous and celebrated composers in world history.
Beethoven showed an aptitude for music at a very early age; from the age of four his father began to teach him. Beethoven's early works - piano sonatas and symphonies - were composed under the strong influence of the music of the great classical composers Joseph Haydn and Wolfgang Amadeus Mozart. As Beethoven matured, however, he began to experiment with new forms and harmonic sequences, and his music became more complex and emotionally charged.
Unfortunately, at the height of his talent, Beethoven began to gradually lose his hearing, to the point of complete deafness by the end of his life. Despite this, he continued to compose and conduct, using special devices to feel the vibrations of the music.
Beethoven's work is considered pivotal in classical music and is a bridge between the classical and Romantic eras. His works vividly express a wide range of emotions, from triumph and joy to sadness and despair. Beethoven was also one of the first composers to include soloists and chorus in his symphonies. Beethoven's best-known works include nine symphonies, 32 piano sonatas, 16 string quartets and the heroic opera Fidelio. These and many other works have cemented Beethoven's place in music history as one of the greatest composers of all time. His music continues to be played and studied by musicians and music lovers around the world.
Publius Vergilius Maro, usually called Virgil or Vergil, was an ancient Roman poet of the Augustan period. He composed three of the most famous poems in Latin literature: the Eclogues (or Bucolics), the Georgics, and the epic Aeneid. A number of minor poems, collected in the Appendix Vergiliana, were attributed to him in ancient times, but modern scholars consider his authorship of these poems as dubious.
Virgil's work has had wide and deep influence on Western literature, most notably Dante's Divine Comedy, in which Virgil appears as the author's guide through Hell and Purgatory.
Virgil has been traditionally ranked as one of Rome's greatest poets. His Aeneid is also considered a national epic of ancient Rome, a title held since composition.
Willem Janszoon Blaeu was a Dutch cartographer and map publisher.
Willem studied astronomy and cartography under the Danish astronomer Tycho Brahe and even discovered the variable star P Swan in 1600. A little later Blaeu settled in Amsterdam, where he began making globes and also began producing land and sea maps, including a 1605 world map. In 1629 he managed to acquire the printing plates of the cartographer Jodok Hondius, with which he published his own atlas.
In 1633, Willem Blaeu was appointed cartographer of the Dutch Republic, as well as the official cartographer of the Dutch East India Company. Blau built up a large collection of maps and conducted an extensive publishing business. After Willem's death, his sons Jan Blaeu (1596-1673) and Cornelius Blaeu successfully continued his work. But in 1672, during a fire in Amsterdam, Blaeu's workshop was destroyed, and the company founded by Willem Blaeu ceased to exist in 1698.
