3 February 1488
Bartolomeu Dias discovered that he had sailed past the southern-most point of Africa. A strong wind had driven him so far south of Cape Point that he did not see it and had to sail northwards to reach the coast. His first landing place was the bay of St. Blaize (SÁƒÂƒ£o Bras), now Mossel Bay. Here he took in fresh water and bartered live-stock from the Khoikhoi. Due probably to a lack of understanding, a crossbow was fired killing one of the Khoi. The Post Office Tree, where seafarers from centuries ago posted letters home using a cleft in an ancient tree as a postbox signifies that ships called regularly at the bay for watering and other purposes.
