Portuguese navigator João da Nova is traditionally credited with discovering Saint Helena in 1502 during his return from India.

Recent scholarship questions whether da Nova actually found the island, noting its absence from contemporary maps and later logs.

João da Nova is traditionally credited with discovering Saint Helena in 1502 during his return voyage from India.
Background and detail
Background. João da Nova was a Galician-born explorer serving Portugal. After engaging in naval battles in the Indian Ocean in late 1501, his fleet departed India around the turn of 1501/2. During this return voyage, he is commonly said to have sighted islands in the South Atlantic, including Saint Helena and Ascension.
Historical Dispute. The traditional discovery date of May 21, 1502, is contested. A 2015 paper suggests this date was first recorded in 1596 and may refer to a Protestant feast day. An alternative date of May 3, 1502, is considered more credible by some scholars, potentially avoiding a name conflict with Cabral's earlier naming of Brazil.
