Portuguese seafarer Bartolomeu Dias enters the wide bay now known as Luderitz Bay after sailing for three weeks along the arid Namibia coast of south west Africa.
On the same day exactly 10 years later, on 25 December 1497, Dias's compatriot Vasco da Gama gave the name Terra do Natal to the coast around the Kei River. The name was later extended to cover the coast up to Durban.
