The Order of Saint James of Altopascio (Italian: Ordine di San Giacomo d'Altopascio or Ordine dei Frati Ospitalieri di San Jacopo), also called the Knights of the Tau (Cavalieri del Tau) or Hospitallers of Saint James, was a military order, perhaps the earliest Christian institution to combine the protection and assistance of pilgrims, the staffing of hospitals, and a military wing. According to American historian Ephraim Emerton, who produced the first systematic study of the Order, "the fame of the house drew visitors, both well and sick, including women in childbirth and infants" from around Italy.
