Wreaths and crowns in antiquity
In classical and late antiquity wreaths or crowns (Ancient Greek: στέφανος, romanized: stéphanos, lit. 'wreath', 'crown'; Latin: corona, lit. 'wreath', 'garland', 'chaplet') usually made of vegetation or precious metals were worn on ceremonial occasions and were awarded for various achievements. The symbolism of these different types of wreaths depended on their composition; different crowns were worn and awarded for different purposes.
