Daily worship of the Lares involved not only the dominus and his family, but also the slaves of the familia. While in small households there might be only one altar to the Lares, used by both free and slave residents, larger households generally had two or more shrines. Shrines used by the dominus and his family could be located in the center of the house,while less elaborate shrines used by the slaves were most often located in the kitchen or in peripheral rooms associated with slaves [note]. Normally the paterfamilias led the daily worship of the household Lares, but should he neglect to do so (or be unable to do so), then another family member would perform the rites. In the prologue of Plautus’ play, the Lar announces that because Euclio, the master of the household, has neglected to perform the daily worship to the Lar,his daughter has taken the responsibility for this office.
