What is the term for the boy attendant in a confarreatio marriage with living parents?

In the context of a confarreatio marriage, which is the ancient Roman form of marriage that involved the exclusive rites and ceremonies of the patrician class, the term used for the boy attendant is "camillus." This role was traditionally fulfilled by a young boy who assisted in the marital ceremonies and helped carry out specific tasks during the rites. The camillus was often a member of the family or a specially chosen boy who played a significant part in the public and religious aspects of the wedding.

The other terms provided have different meanings: "puer" generally refers to a boy or youth but does not specify any ceremonial duties; "filius" means son, which indicates a relationship but not a specific role in marriage ceremonies; and "servus" refers to a servant. None of these terms refer specifically to the attendant in the context of confarreatio marriage ceremonies. Therefore, camillus is the correct term for the boy attendant in this context.
