Syphilis in the 16th century―Excavated examples of Katsuyama castle―

１6 世紀のsyphilis―勝山館跡の出土事例から―

Abstract
　A case study of 16th-century bone syphilis excavated from the site of the Katsuyama castle located in Kaminokuni town, southwestern Hokkaido. Takao Suzuki, who examined the human bones, determined from the morphological characteristics that the four human bones belonged to the same mature man, and from the findings of the bulging (thickening) accompanied by osteosclerosis with a smooth bone surface, he diagnosed ostesyphilis.
　In addition, several burial tombs have been constructed in the area where the bones were excavated, but the person suffering from syphilis was not buried in the grave. Regarding the burial of people with syphilis, it is known that they were buried in pots in the edo period. The case excavated of Katsuyama castle is a valuable example in considering the way people thought about syphilis and the funeral procession in the muromachi period.
