"Alasdair was an extraordinary person; very talented and, even more importantly, very humane.
"He was unique and irreplaceable and we will miss him greatly.
"We would like to thank Alasdair’s many friends for their love and support, especially in recent years.
"Together with the staff of the Queen Elizabeth hospital, Glasgow, who treated him and us with such care and sensitivity during his short illness.
"In keeping with his principles Alasdair wanted his body donated to medical science, so there will be no funeral.”

First minister Nicola Sturgeon wrote on Twitter: "While many of us will think of Alasdair Gray first and foremost as a brilliant and innovative writer, he was also a hugely talented artist.
"A true polymath, he was one of the brightest intellectual and creative lights Scotland has known in modern times. RIP"
Francis Bickmore, Gray’s editor and publishing director at Canongate, said: “What sad news this is that Alasdair Gray is gone.
"It seems hard to believe that Alasdair was mortal and might ever leave us.
"No one single figure has left such a varied legacy – or missed so many deadlines – as Alasdair Gray.
Like Blake, the project Alasdair was immersed in when he died was his version of Dante’s Comedia. Last time I saw him he read some of it. I suspect he is well prepared for the journey he’s on now. pic.twitter.com/qrfhlccGWf

"At least through Gray’s phenomenal body of work he leaves a legacy that will outlive us all.
"His voice of solidarity and compassion for his fellow citizens, and his forward-looking vision is cause for great celebration and remembrance.”
His agent Jenny Brown said: “We mourn Alasdair Gray’s passing, but his genius will live on for readers through his remarkable work.
"He was a cultural trailblazer: nobody has done more to spur on, and give confidence to, the next generation of Scottish writers.”
Belle and Sebastian singer songwriter Stuart Murdoch wrote: "Farewell to Alasdair Gray, Scotland’s great creator.
"We’ll miss you for your art, we’ll miss you for your stories, we’ll miss you for your humanity."

The writer and artist was a familiar figure over the years around the West End.
Passers by would often see him working away in the window of his West End home on his latest painting.
The author Julie Bertagna said on social media: "I often used to see Alasdair Gray among his paintbrushes, two doors down from my old student flat.
"He’s part of the fabric of Glasgow’s West End and always will be."
One of his public appearances in recent years was as a guest of the Creative Writing department at the University of Glasgow.
The department said: "When Alasdair Gray was our guest for #CreativeConversations the chapel was packed with a rapt audience and he had us all laughing with delight.
"He’ll be sorely missed."
And professor of creative writing at the university Louise Welsh remembered: "A wonderful day.
"People at the back of @UofGlasgow chapel stood on chairs to get a better look.
"Alasdair insisted on signing everyone's books which took well over an hour.
"He read from his translation of Dante & the 300+ audience were silent."
