The first ascent of the volcanic cone is documented for the 13th century. The Dominican friar Burchard of Mount Sion, in his pilgrimage report to the Holy Land, tells of his return journey via Sicily, which probably took place in 1284. On Vulcano he had climbed the summit "crawling on his hands and feet".[1] His ascent can be considered authentic, as he reports in detail on his observations of the landscape and nature, for example describing the fumaroles or the diameter of the crater.[citation needed]
