The Palestrina Mosaic or Nile mosaic of Palestrina is a late Hellenistic floor mosaic depicting the Nile in its passage from the Blue Nile to the Mediterranean. The mosaic was part of a Classical sanctuary-grotto in Palestrina, a town east of Ancient Rome, in central Italy. It has a width of 5.85 metres and a height of 4.31 metres and provides a glimpse into the Roman fascination with ancient Egyptian exoticism in the 1st century BC, both as an early manifestation of the role of Egypt in the Roman imagination[1] and an example of the genre of "Nilotic landscape", with a long iconographic history in Egypt and the Aegean.
