Romans in sub-Saharan Africa
According to Pliny the Elder, an expedition of Mauretanians sent by Juba II visited the islands. Juba II dispatched a contingent to re-open the dye production facility at Mogador (historical name of Essaouira, Morocco) in the early 1st Century and subsequently explored the Canary Islands, Madeira, and possibly the Cape Verde islands, using Mogador as their base.
