A famous painting in the National Gallery by Paul Delaroche depicts the execution of which woman?

The Execution of Lady Jane Grey is an oil painting by Paul Delaroche completed in 1833 in the National Gallery in London, although as of August 2017 it is on loan to a gallery in Japan. It was enormously popular in the decades after it was painted, but in the 20th century realist historical paintings fell from critical favour and it was kept in storage for many decades, for much of which it was thought lost. Restored and displayed again since 1975, it immediately once again became a highly popular work, especially with younger visitors.

The painting portrays, erroneously in some regards, the moments preceding the death of Lady Jane Grey, who on 10 July 1553 was proclaimed Queen of England, only to be deposed nine days later and executed in 1554. Jane is sometimes referred to as the "Nine Days' Queen" due to the brevity of her reign.
