However, the town was spoken as Manbai within the Mirat-i-Ahmadi, a historical text on Gujarat dating back to 1507 written in Persian by Ali Muhammad Khan. In Lendas da Índia or the Legends of India, written in old Portuguese by writer Gaspar Correia, the town was mentioned as Bombaim, meaning ‘good bay’. ‘Bombay’ is an anglicized version of the Portuguese name employed by British when they took control of the town within the 17th century.
