Anne Boleyn won the heart of King Henry VIII, gave birth to one of the country's most well-known monarchs, and lost her head in 1536 - but her appearance has continued to challenge art historians and online sleuths.
Now a computer science team believes they have discovered a previously unknown sketch of Boleyn by using facial recognition on a famous collection of Tudor portraits.
Boleyn became Henry VIII's second wife in 1533, but her reign was short-lived: approximately three years. She was accused of adultery, incest and treason and was executed.
All the painted portraits that exist of her were made after her lifetime, creating a mystery around what she actually looked like and making her appearance the subject of fascination and debate for centuries.
The research team, led by the University of Bradford, says the new discovery is "exciting" and the methodology could be replicated to do more art detective work. But there is scepticism from within the art history community over the findings.
