Each Greek warrior (Hoplites, Spartans and Macedonians) provided his own equipment. Thus, only those who could afford such weaponry fought as hoplites; Equipment was not standardised, although there were doubtless trends in general designs over time, and between city-states. The shield was decorated with family or clan emblems, although in later years these were replaced by symbols or monograms of the city states. The equipment might well be passed down in families, since it would have been expensive to manufacture.
