Juba II
The island's indigenous people, the Guanche Berbers, referred to the island as or in their language (variant spellings are found in the literature). According to Pliny the Younger, Berber king Juba II sent an expedition to the Canary Islands and Madeira; he named the Canary Islands for the particularly ferocious dogs () on the island. Juba II and the ancient Romans called the island of Tenerife , from the Latin word (nsg.; gsg. , npl. ), meaning "snow", after the snow-covered peak of the Mount Teide volcano. Later maps dating to the 14th and 15th century, drawn by mapmakers such as Bontier and Le Verrier, called the island , ("Hell Island"), due to Mount Teide's volcanic eruptions and other volcanic activity.
