Some have refused to see in such cases any real correspondence with the modern forms of syphilis because only local effects are described and no constitutional consequences traced. But no one in those times thought of a primary focus of infection with its remoter effects at large, in the case of any disease whatsoever. Even in the great epidemic of syphilis at the end of the fifteenth century, the sequence of primary and secondary (tertiaries were unheard of until long after), was not at first understood; the eruption of the skin, which was compared to a bad kind of variola, the imposthumes of the head and of the bones elsewhere, together with all other constitutional or general symptoms, were traced, in good faith, to a disordered liver, an organ which was chosen on theoretical grounds as the _minera morbi_ or laboratory of the disease[147]. The circumstances of the great epidemic were, of course, special, but they were not altogether new. No medieval miracle could have been more of a suspension of the order of nature than that _luxuria_, _immunditia_, and _foeditas_, with their attendant _corruptio membrorum_, should have been free from those consequences, in the individual and in the community, which are more familiar in our own not less clean-living days merely because the sequence of events is better understood. That such vices abounded in the medieval world we have sufficient evidence. They were notorious among the Norman conquerors of England, especially notorious in the reign of William Rufus[148]; hence, perhaps, the significance of the phrase _lepra Normannorum_. That particular vice which amounts to a felony was the subject of the sixth charge (unproved) in the indictment of the order of the Templars before the Pope Clement V. in 1307. Effects on the public health traceable to such causes, for the most part _sub rosa_, have been often felt in the history of nations, from the Biblical episode of Baal-peor down to modern times. The evidence is written at large in the works of Astruc, Hensler and Rosenbaum. We are here concerned with a much smaller matter, namely, any evidence from England which may throw light upon the classes of cases that were called leprous if they were called by a name at all.
