full_context: Document 1: Emil Pollert: Emil Pollert, born Emil Popper (20 January 1877, Liblice at Mělník – 23 October 1935, Prague) was a Czech opera singer at the National Theatre in Prague, in his time the main representative of bass roles.
Document 2: Prague astronomical clock: The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410 when it was made by clockmaker Mikuláš of Kadaň and Jan Šindel, then later a professor of mathematics and astronomy at Charles University. The first recorded mention of the clock was on 9 October 1410. Later, presumably around 1490, the calendar dial was added and the clock facade was decorated with gothic sculptures.
Document 3: Time: The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (1525–1504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.
Document 4: Praha Masarykovo nádraží: It was the first railway station in the city to serve steam trains, and the second oldest railway station in Prague, Czech Republic (the first is Praha-Dejvice, formerly Bruska on the Lány Horse-drawn Railway).

Document 7: Computer: Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use. The planisphere was a star chart invented by Abū Rayhān al-Bīrūnī in the early 11th century. The astrolabe was invented in the Hellenistic world in either the 1st or 2nd centuries BC and is often attributed to Hipparchus. A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer and gear-wheels was invented by Abi Bakr of Isfahan, Persia in 1235. Abū Rayhān al-Bīrūnī invented the first mechanical geared lunisolar calendar astrolabe, an early fixed-wired knowledge processing machine with a gear train and gear-wheels, circa 1000 AD.

Document 13: Cubism: The leading Cubist architects were Pavel Janák, Josef Gočár, Vlastislav Hofman, Emil Králíček and Josef Chochol. They worked mostly in Prague but also in other Bohemian towns. The best-known Cubist building is the House of the Black Madonna in the Old Town of Prague built in 1912 by Josef Gočár with the only Cubist café in the world, Grand Café Orient.

There is only one country in the world where Cubism was really applied to architecture – namely Bohemia (today Czech Republic) and especially its capital, Prague. Czech architects were the first and only ones in the world to ever design original Cubist buildings. Cubist architecture flourished for the most part between 1910–1914, but the Cubist or Cubism-influenced buildings were also built after the World War I.
