First of all, since the concept of class warfare derives from dialectical materialism (a 19th-century philosophy of history), we can't impose it on the ancient world as such. At best, we'd be looking at something that we interpret as class warfare without actually knowing whether the class consciousness of the people involved had much to do with it.

So can the myth of Theseus and the Minotaur be interpreted as class warfare? I'm sure it is possible; if Suzanne Collins can say that the Theseus myth inspired her story of popular uprising triggered by a sadistic killing game, I'm sure there are at least some Marxists out there who see it as an ancient story of a repressed proletariat rising up against its masters. At the very least, it involves people forced to pay a regular tribute of their own children to a foreign overlord. Did they have nothing else with which to pay? Doesn't that mean they are proletarians?

On the other hand, there is a slight problem: Theseus was of royal blood too. He was the son of King Aigeus of Athens, and destined to become king himself. The whole story of the tribute paid to Minos was allegedly borne out of the assassination of King Minos' son, for which the Athenians were to do penance by sending their most beautiful young men and women as sacrifices to Crete every seventh (or ninth) year. While we may read into this the existence of an ancient Minoan empire imposing tribute on other Greeks - as Thucydides already did in the 5th century BC - we certainly can't interpret it as the oppression of a working class by a ruling class. It was the entire community of Athens that was subjected to the power of Minos, royal house and all.

Indeed, the particular way in which Harmon claims this should be seen as class war cannot possibly work. He suggests that the entire story originated with primitive Athenians misunderstanding the meaning and purpose of Cretan bull's head coins. These coins were supposedly some of the advancements made by the people of Knossos when they "burst into the Bronze Age". However, the earliest known coins in the world date to about 600 BC - a good two thousand years after the start of the Bronze Age, and some 500 years into the Iron Age. They are also not made of bronze, but of electrum (a natural mix of silver and gold). They also do not seem to have been invented on Crete (both ancient authors and modern archaeology suggest they were invented in Lydia in Western Asia Minor). It is clear that bronze-working technology did not lead to the invention of currency (in Crete or anywhere else); the entire suggestion of primitive peoples dazzled by bronze coins is pure creative writing.
