The earliest toys were made from rocks, sticks or clay. In Ancient Egypt, children played with dolls made of clay and sticks. In Ancient Greece and Ancient Rome, children played with dolls made of wax or terracotta, sticks, bows and arrows, and yo-yos. Later these developmental games were used in creation of indoor playsets for homes. When Greek children, especially girls became adults, it was required to sacrifice the toys to the gods. On the eve of their wedding, young girls around fourteen would offer their dolls in a temple as a rite of passage into adulthood.
