Possibly from Florence, he was a soldier under Henry VIII and visited Venice in 1549 on royal business. He returned to Italy, but was in England by 1562, seeking patronage and working as a scribe. By 1577, he had a royal pension; gifts of MSS to Queen Elizabeth probably gained her support against creditors. His works were printed in Italian and English by J. Wolfe and R. Field in London—his account of the Spanish Armada being particularly successful.
