The ten-year-old Lambert Simnel is crowned in Christ Church Cathedral, Dublin, Ireland, with the name of Edward VI in a bid to threaten King Henry VII's reign.

Lambert Simnel was a pretender to the throne of England. In 1487, his claim to be Edward Plantagenet, 17th Earl of Warwick, threatened the newly established reign of Henry VII (1485–1509). Simnel became the figurehead of a Yorkist rebellion organised by John de la Pole, Earl of Lincoln. The rebellion was crushed in 1487. Simnel was pardoned because of his tender years, and was thereafter employed by the royal household as a scullion.

Christ Church Cathedral, more formally The Cathedral of the Holy Trinity, is the cathedral of the United Dioceses of Dublin and Glendalough and the cathedral of the ecclesiastical province of the United Provinces of Dublin and Cashel in the (Anglican) Church of Ireland. It is situated in Dublin, Ireland, and is the elder of the capital city's two medieval cathedrals, the other being St Patrick's Cathedral.

Henry VII, also known as Henry Tudor, was King of England and Lord of Ireland from his seizure of the crown on 22 August 1485 until his death in 1509. He was the first monarch of the House of Tudor.
