The Trajan's Column is one of the most impressive triumphal monuments ever built and is one of the most complete works carved in stone (marble) that antiquity has left to the world. The monument was erected in 106-113 AD by the Roman Emperor Trajan. Today, the column survives intact in the ruins of Trajan's Forum in Rome.
Pietro Santi Bartoli (1635-1700) put scaffolding around Trajan's Column and proceeded to climb it. In the 17th century, for months and months, the corpulent artist and climber explored the huge storiated pillar, whose forty meters of height is wrapped in two hundred meters of a spiralling frieze.
