Sir Philip Sidney was a prominent figure of the English Renaissance—soldier, courtier, diplomat, and one of the most celebrated poets of Elizabethan England. Born into an influential family, Sidney moved in the highest political and literary circles of Queen Elizabeth I’s court. His best-known works include Astrophil and Stella (a sonnet sequence), The Defence of Poesy (an early work of literary criticism), and Arcadia (a pastoral romance). Despite his literary legacy, Sidney died young at 31, from a wound sustained in battle in the Netherlands. His death was widely mourned, and he was remembered as the ideal "Renaissance man," combining intellect, artistry, and chivalric valor.
