Many saints are shadowy figures. There is admittedly usually what purports to be a “life”, but that is generally hagiography, following stock topoi: birth, acts of healing and other miracles, death (perhaps as a martyr), and posthumous miracles. Such accounts often share details with other saints or, on occasion, with mythical figures not necessarily Christian. Thus, England’s own patron saint, St George, may in part be descended from a pagan hero such as Bellerophon. Francis is different.
