Entries are invited by 12 November for the Crowley Colosso Leonardo Prize. This is awarded under the patronage of the Accademia Italiana to the dealer who has made the most important rediscovery or reattribution of an Italian work of art. Last year's winner was Clive Gill of Sarice Antiques, Tunbridge Wells, who purchased at a local auction a previously unrecorded astronomical and astrological manuscript of around 1455, probably made in Rimini. This year's winner will be announced on 7 December. The prize includes a trip to Italy with tours of museums and private collections. Entries to the Accademia, 24 Rutland Gate, London SW7.
