A rediscovered portrait of a teenage Bonnie Prince Charlie disapproved of by his father because he looked too confident is to go on public display in Scotland for the first time.

The National Museum of Scotland has secured a loan of a painting that Charles Edward Stuart sat for in Venice when he was just 16.

It is said to be significant because it was not supervised by his father, the exiled James VIII, and therefore likely to be a more accurate representation.

Renowned Venetian artist Rosalba Carriera painted the portrait, believed to be the only depiction of Charles predating the 1745 Jacobite rising which wasn't painted in Rome.

Carriera painted Charles - also known as the The Young Pretender - in 1737 while he was in Venice on a tour of the major cities in central and northern Italy.

The portrait was disliked by his father because he said the prince looked unusually mature and confident for his age.

It was sent to King James in Rome who later gifted it to a friend who was a member of an esteemed Roman family.

It remained in a private collection unknown to the general public until it was auctioned in 2018 for £29,000.

It was purchased by Warsaw-based art historian, Peter Pininski, who claims to be a direct descendant of the prince, and lent to the National Museum of Scotland in Edinburgh.

The museum is putting the portrait on display alongside the prince's silver canteen of travelling cutlery and shield from tomorrow until May 27.

A spokeswoman for National Museums Scotland said: "It was painted without the undue influence of his father and is believed to be the closest representation of him.

"James gave the portrait away quite quickly which would lead one to assume he didn't like it.

"It was given to a prominent Roman family at that time.

"Some of the paintings are of Charles looking a little older and the artists often painted how they thought he would look in five years.

"This painting is important because it was painted in Venice and didn't have the influence of his father."
