AN Oxford University college has offered a £3,500 reward for the return of a ring, once owned by Oscar Wilde, which was stolen in a raid.

Magdalen College is appealing for the return of an 18-carat gold friendship ring given by Wilde, who studied at the college, and Reginald Harding to William Ward.

The three men were close friends at university. Wilde used to call Harding "Kitten", and the ring forms part of an extensive collection of Wilde memorabilia owned by Magdalen. The ring has a Greek inscription on the inside and the initials: OF OF WW + RRH to WWW 1876.

The thieves also took a Henley Royal Regatta Grand Challenge Cup medal, from 1910, which was won by M M Cudmore; and a silver and a bronze medal presented to R F G Sarell in 1932.

The raid took place early on Thursday, May 2, after the college porter went to investigate an alarm. While he was away, the thief struck in another part of Magdalen, taking the ring from a display cabinet.

Police fear the thief may not realise the historical significance of the ring and have urged antique dealers and jewellers to look out for it.

The £3,500 reward, for information leading to the ring's return, is subject to certain conditions.

The home bursar of Magdalen College, Mark Blandford-Baker, said: "This is a very important part of of the collection of Oscar Wilde memorabilia owned by the college and it is a sad loss.

"A friendship ring like that is only worth a few hundred pounds, but its value to our heritage is rather different."
