This is Spartaaaa!!!!!!!!!!

I have seen this one in several places and I love it.

It seems to be a reference to the 300 Spartans who fought the Persians of Xerxes in the Battle of Thermopylae.
They are now a very well-known story in terms of pop-cluture, thanks to a comic and a 2007 film.

The battlefield here is a 16x16 chessboard (that is 256 squares, or 4 conventional chessboards) in which our 300 Greeks [White] are represented by quite standart material in terms of Rooks, Knights and Bishop (2 of each class), 10 Pawns, 2 Queens, and 3 Kings (one of them a human head, shouting).

The Persian side [Black] is composed by eight ranks of soldiers. When you add the material that gives you 64 Pawns, 16 Rooks, 16 Bishops, 16 Knights, 8 Quuens and 8 Kings. A total 128 chess pieces.

But you know the beauty in chess resides in victory of the spirit over the material. A very appropiate metaphor.
