In 2005 Dali's Christ of St John of the Cross was voted Scotland's favourite painting in the Herald newspaper, but it's had a torrid relationship with its home city of Glasgow over its near 60 year existence.
It was bought for the then shocking price of £8,200 by Dr Tom Honeyman, the head of the city's art galleries in 1952.
But Honeyman was no ordinary curator and the Dali was no ordinary painting.
From the start there was uproar: art students, religious zealots and critics were all appalled that Honeyman had spent so much money and bought this atypical Dali with its mesmerising stigmata-less, floating crucifixion.
But Honeyman was defiant: not for him the baggage of an elitist arts background, he had trained and practised as a Glasgow doctor among the poor of the city.
He saw himself as a showman, whose job was to show pictures and to pull the people in.
He recognised from the first the unique pulling power of this extraordinary painting which has stormed the hearts of Glaswegians.
Using extracts from the Honeyman Papers at National Library of Scotland read by Bill Paterson we hear Honeyman's thoughts along with the those of the Glasgow public who love the painting.
It can't be so much as moved within the gallery without exciting comment and opinion from the public to whom it is THEIR painting - how dare some curator move it! How to explain such an extraordinary outpouring of feeling about a single work of art? Crime writer Louise Welsh gets on the case to examine the remarkable love/hate affair between Glasgow and the Dali.
The Dali Christ is Scotland's favourite painting.
