One is an alternative version of Da Vinci's famous painting known as Virgin of the Rocks, with the infant Jesus and the infant John the Baptist. The other shows Mary Magdalene, thought to have been completed by Leonardo with the help of one of his pupils about 1515, shortly before his death.
Both are being displayed at Ancona's Mole Vanvitelliana museum. The semi-naked painting of Mary Magdalene - on a wooden panel - has fascinated critics and has only recently been discovered and authenticated, says the BBC's Rome correspondent, David Willey.
Previously attributed to Da Vinci's pupil Giampietrino it has been in private collections for nearly all its recorded history in the past 100 years. The Virgin of the Rocks, painted with Giampietrino between 1495 and 1497, has two other versions - one kept at the Louvre in Paris and the other in London's National Gallery.

~ I think this is quite interesting. This third painting resembles the Luvre version more than the National Gallery one, but still has the halo around the virgin Mary, with the main difference being the colour of her cloak being green as opposed to blue in the other two versions.
See for yourself.
