Socrates explains :
"You know, Phaedrus, that is the strange thing about writing, which makes it truly correspond to painting.
The painter's products stand before us as though they were alive,
but if you question them, they maintain a most majestic silence.
It is the same with written words; they seem to talk
to you as if they were intelligent, but if you ask them anything
about what they say, from a desire to be instructed,
they go on telling you just the same thing forever".
The Alexander Mosaic, dating from circa 100 BC, is a Roman floor mosaic originally from the House of the Faun in Pompeii. It depicts a battle between the armies of Alexander the Great and Darius III of Persia and measures 2.72 by 5.13 metres (8 ft 11 in × 16 ft 10 in). The original is preserved in the Naples National Archaeological Museum. The mosaic is believed to be a copy of an early 3rd-century BC Hellenistic painting.
