The dazzling research of a master economic historian--ranging from forgotten 19th century operas to the diaries of visiting Venetian nobles at the Lisbon court, from 20th century Bengali novelists to anonymous chroniclers aboard the Sao Gabriel (Vasco da Gama's vessel)--shines through this almost racy biography. Subrahmanyam does not need the security of stereotypical explanatory frameworks. He oscillates skilfully between legend and fact to create a finely nuanced portrait of the 15th century 'Argonaut'. In doing so, he reaches several universal conclusions about why nations create heroes: not only to bolster international prestige but also to establish a greater 'national' truth that is able to harness to itself the energies of a powerful and quarrelsome ruling class. The cult of heroes also sanctifies the authority of he who aspires to be supreme ruler of the 'nation'--in this case, Dom Manuel of Portugal.
