'Biggest' gathering of bishops to honour Orkney's saint
Three Roman Catholic archbishops and nine bishops have celebrated Mass in St Magnus cathedral in Kirkwall.
The service was the culmination of a pilgrimage by the diocese of Aberdeen.
They were in Orkney to mark the 900th anniversary of the martyrdom of Magnus, joint earl, who was killed on his cousin's orders.
The anniversary has been marked by a number of other events, including the setting up of the Magnus Way pilgrimage route.
It is believed to be the biggest gathering of bishops and archbishops in Orkney's history.
St Magnus was killed in the island of Egilsay by his cousin Haakon.
The year of his martyrdom is not known with certainty, but the most probable is 1117.
Magnus was declared a saint about 20 years after his death. His nephew, St Rognvald, built St Magnus Cathedral in his memory, starting in 1137.
In his homily, Bishop of Aberdeen Hugh Gilbert drew a parallel between Jesus's teaching that a grain has to fall into the ground and die before it can produce sheaves of wheat to harvest, and the murder of Magnus.
He said Magnus's death had produced a legacy of peace; wellbeing and healing; and creativity.
The service included the playing of Ivan Drever's "Rose of St Magnus" inspired by the rose window of the cathedral, and the singing of the medieval hymn to Magnus "Nobilis humilis".
Afterwards, the minister of the cathedral, the Rev Fraser Macnaughton, told BBC Radio Orkney the service gave a flavour of what life would have been like in the building before the Reformation because, he said, it had been a Catholic cathedral for more than 500 years.
