Aristion\'s tombstone

[hoplite14gr]

The outer layer could always been painted. The Alexander Mosaic indicates that Alexander's linothorax was painted purple.
Argives tried to keep the outer layer white.
The Spartans are reputed to paint th outer layer red.

Purple definetly would be for the elite troops or royalty.

The Vergina tomp finds indicated the even metal objects (helmets) could be painted.

Hope it helps
Kind regards
