The Romans worshiped many different gods and goddesses. They were all part of one big family but they each looked after a different part of life:
To keep the gods happy, Romans would make offerings of: food, flowers or money at special buildings called temples. Sometimes a priest would kill an animal like a bull or sheep as a sacrifice.
Many families would have shrines in the homes to particular gods so that they could pray to them for good luck and protection.
Roman people also looked for messages sent by the gods - especially before starting something important like setting off on a journey or declaring war. Messages could be read: in the weather, in mysterious events like eclipses and in animals.
