Ancient Greek clothing was typically homemade from undyed wool or linen fabrics that served as both garments and blankets. These fabrics were intensely colored and featured detailed designs based on artwork from the period. Music was an important part of Greek culture and commonly featured in theater, being played during choral performances. The early Greek theater involved only three actors and no speaking roles; over time, roles expanded. Tragedy, comedy, and satyr plays were the main theatrical forms. Greek mythology explained the origins and behavior of the gods, goddesses, heroes, and the natural world, playing a role in Greek religion.
