How is the minoan painting of children boxing similar to work from other cultures?

A Minoan fresco Akrotiri on Thera, an Aegean island, shows two boys boxing. They are almost nude, except for a loincloth, and have red bodies, and they are shown punching each other in the head. Their long hair with partly shaved heads is associated with youth.
This image and the style of fighting can be compared to depictions of male youths boxing in ancient Greece. Pygmachia was one type of boxing featured in the Olympics and other Panhellenic festivals. It was mentioned in Homer’s Iliad. Ancient Greek ceramic vases, or amphorae, depict boxers; the figures are usually black on an orange ground. The fighters’ bodies are nude, and their hands are wrapped in with leather bands. Bronze sculptures also show boxers with these bands.
