He left an account of the disaster hidden in an old shoe which he suspended from a milkwood tree (Sideroxylon inerme) near the spring from which explorer Bartolomeu Dias had drawn water. The report was found by the explorer to whom it was addressed, João da Nova, and the tree served as a kind of de facto post office for decades thereafter. João da Nova erected a small shrine near the Post Office Tree, and although no traces of it remain, it is considered the first place of Christian worship in South Africa.
