vaults, completed about the same time, and thought to be by the same sculptor, feature the green man common to the folklore of the British Isles. The presence of English coins contemporary with that period on the site indicate the involvement of English artists at work in the region. Further embellishment of the church took place in 1330, when the tympanum of the south portal was decorated with relief scenes from the Nativity and the Passion, in a German style. The present day The cathedral has a significant 16th century altarpiece by Dutch Golden Age painter Maarten van Heemskerck, Crucifixion, a polyptych painted for Sint-Laurenskerk, Alkmaar. Begun in 1538 and completed in 1542, the artwork was first installed in the church in Alkmaar; the onset of the Reformation led to its removal and in 1581 it was sold. In 2006, British artist Brian Clarke was commissioned to design six stained glass windows for the north and south porches of the cathedral's transept: three lancets above the porch entrances on each side. Funded by the Bernhard Risberg Donation Fund, created in 1947 "for the beautification of Linköping Cathedral", the windows were installed in September 2010. In popular culture The cathedral is featured on the cover of the album Opus Eponymous by Ghost, whose founder, Tobias Forge, is a native of Linköping.
