There were many different types of guardians. The most important are the Lares Familiares (guardians of the family), Lares Domestici (guardians of the house), Lares Patrii and Lares Privati. Other guardians were the Lares Permarini (guardians of the sea), Lares Rurales (guardians of the land), Lares Compitales (guardians of crossroads), Lares Viales (guardians of travelers) and Lares Praestitis (guardians of the state). The Lares are usually depicted as dancing youths, with a horn cup in one hand and a bowl in the other. As progenitors of the family, they were accompanied by symbolic phallic serpents.
Roman guardian spirits of house and fields. The cult of the Lares is probably derived from the worshipping of the deceased master of the family. It was believed that he blessed the house and brought fertility to the fields. Just like the Penates, the Lares were worshipped in small sanctuaries or shrines, called Lararium, which could be found in every Roman house. They were placed in the atrium (the main room) or in the peristylium (a small open court) of the house. Here people sacrificed food to the Lares on holidays. In contrast to their malignant counterparts the Larvae (Lemures), the Lares are beneficent and friendly spirits.
