Sir Robert Dudley, the handsome 'base born' son of Elizabeth I's favourite, was born amidst scandal and intrigue. The story of his birth is one of love, royalty and broken bonds of trust. He was at Tilbury with the Earl of Leicester in 1587; four years later he was wealthy, independent and making a mark in Elizabeth's court; he explored Trinidad, searched for the fabled gold of El Dorado and backed a voyage taking a letter from the queen to the Emperor of China. He took part in the Earl of Essex's raid on Cadiz and was implicated in the earl's rebellion in 1601 but what he wanted most was to prove his legitimacy.
Refusing to accept the lot Fate dealt him after the death of the Queen, he abandoned his family, his home and his country never to return. He carved his own destiny in Tuscany as an engineer, courtier, shipbuilder and seafarer with the woman he loved at his side. His sea atlas, the first of its kind, was published in 1646. The Dell'Arcano del Mare took more than twelve years to write and was the culmination of a lifetime's work. Robert Dudley, the son Elizabeth never had, is the story of a scholar, an adventurer and Elizabethan seadog that deserves to be better known. '
