Titian masterpiece Diana and Callisto saved for nation

Titian's Diana and Callisto has been saved for the nation after a £45m deal was agreed with owner the Duke of Sutherland.

The "supremely important" oil painting was bought with the help of £25m from the National Gallery after a lengthy fundraising campaign.

Campaigners had already secured funds to buy sister piece Diana and Actaeon, for £50m, from the Duke in 2009.

The National Gallery hailed the "exceptional generosity" of donors.

It had been given until the end of the year to raise money for the second Titian work.

Diana and Callisto and Diana and Actaeon were produced in the 1500s by Renaissance artist Titian - full name Tiziano Vecelli - and are considered to be among his greatest works.

The paintings are among six large-scale works, painted for Philip II of Spain, that are inspired by Roman poet Ovid.
