13 septembrie: Ziua în care Michelangelo a transformat un bloc de marmură abandonat de alți sculptori în statuia lui David

On September 13, 1501, Michelangelo began sculpting David from a discarded marble block, creating a Renaissance masterpiece. In 1913, Aurel Vlaicu, a pioneer of aviation, died in a plane crash while attempting to cross the Carpathians. The same date marks the annual celebration of Romania's Firefighters' Day, honoring those who fought in the 1848 Battle of Dealul Spirii. Additionally, Tupac Shakur, a significant figure in hip-hop, was killed on September 13, 1996, at the height of his career. The day is also associated with the first apparition of the Virgin Mary in Fatima, Portugal, in 1917.
