A Spanish court has ordered that the remains of Surrealist artist Salvador Dalí be exhumed to carry out a paternity test. According to the BBC, a Madrid judge ruled that because there are no other known biological remains that could be used to carry out the test, his body would have to be exhumed.

“The DNA study of the painter’s corpse is necessary due to the lack of other biological or personal remains with which to perform the comparative study,” the decision read, according to the Guardian.

Maria Pilar Abel Martínez, a tarot card reader who was born in 1956, first publicly claimed to be Dalí’s daughter in 2015. She says her mother had been a maid for a family in Cadaqués in 1955, where the artist was living at the time with his wife Gala Dalí (the Dalís never had children).
