A significant modification of Cubism between 1914 and 1916 was signaled by a shift towards a strong emphasis on large overlapping geometric planes and flat surface activity. This grouping of styles of painting and sculpture, especially significant between 1917 and 1920, was practiced by several artists; particularly those under contract with the art dealer and collector Leonce Rosenberg. The tightening of the compositions, the clarity and sense of order reflected in these works, led to its being referred to by the critic Maurice Raynal (fr) as 'crystal' Cubism. Considerations manifested by Cubists prior to the outset of World War Isuch as the fourth dimension, dynamism of modern life, the occult, and Henri Bergson's concept of durationhad now been vacated, replaced by a purely formal frame of reference.

Ex Output:
What did the critic Maurice Raynal begin to refer to Cubism in around 1917-1920?

The 197374 season saw the arrival of Johan Cruyff, who was bought for a world record 920,000 from Ajax. Already an established player with Ajax, Cruyff quickly won over the Barcelona fans when he told the European press that he chose Barcelona over Real Madrid because he could not play for a club associated with Francisco Franco. He further endeared himself when he named his son Jordi, after the local Catalan Saint George. Next to champions like Juan Manuel Asensi, Carles Rexach and Hugo Sotil, he helped the club win the 197374 season for the first time since 1960, defeating Real Madrid 50 at the Bernabeu along the way. He was crowned European Footballer of the Year in 1973 during his first season with Barcelona (his second Ballon d'Or win; he won his first while playing for Ajax in 1971). Cruyff received this prestigious award a third time (the first player to do so) in 1974, while he was still with Barcelona.

Ex Output:
When did Johan Cruyff join Barcelona?

The Monument in the City of London provides views of the surrounding area while commemorating the Great Fire of London, which originated nearby. Marble Arch and Wellington Arch, at the north and south ends of Park Lane respectively, have royal connections, as do the Albert Memorial and Royal Albert Hall in Kensington. Nelson's Column is a nationally recognised monument in Trafalgar Square, one of the focal points of central London. Older buildings are mainly brick built, most commonly the yellow London stock brick or a warm orange-red variety, often decorated with carvings and white plaster mouldings.
