 The Brotherhood is supposed to have consisted of three branches-- knights, clergy and artisans, where the knights usually had contributed most of the funds and were sometimes called "donati", the clergy were usually monks who represented the church, and the artisans were the workers who actually built the bridges.Sisters are sometimes mentioned as belonging to the same association.In addition to the construction of bridges, the brotherhood allegedly often attended to the lodging and entertainment of travelers and the collection of alms or "quête".
