A 15th Century Italian Renaissance prayer book valued at £10m has finally been completed after a stolen page was reunited with the rest of the volume. The intricately illustrated Sforza Hours was commissioned around 1490 but at least three pages were stolen from the illuminator before its completion. The missing pages were discovered 65 years ago and until this year one remained in private hands. ... The book measures just 130mm x 95mm but is considered one of the library's greatest treasures. It contains an illustrated calendar marking religious days alongside illustrations for each month. The final page - October - is illustrated with a hunting scene, a typical activity for the time of year. BBC
