For
#MosaicMonday, a colossal discovery. This is the Great
#Mosaic, which I visited last Tuesday beneath the
#BathsofTrajan in
#Rome. Though fragmentary, this wall mosaic almost defies comprehension due to its quality and vastness. Let's have a look.🧵
ALT HALL OF THE GREAT MOSAIC, 64-98 CE. MUSEO DELLE TERME DI TRAIANO
A steep downward perspective into a subterranean space beneath heavy brick vaulting. A vast vertical wall dominates the centre, covered in the remains of a monumental mosaic. This hall measures 10 by 15 metres and is 12 metres tall. The ground level has not yet been excavated, and the lower three metres, still buried, were originally faced with marble slabs. At the centre of the long wall, part of a rectangular niche is visible, which must once have contained a statue. It is far too large to be part of a private domus and is built on lands expropriated by Nero for the Domus Aurea, whose main Oppian pavilion is nearby. The gigantic size and high quality of the surviving mosaic suggest an imperial commission, but of what? And was it a Neronian building or a Flavian or Domitianic one? At the very bottom right edge, a modern blue metal railing provides a sense of the staggering scale.
