The 43-year-old will contemplate things "lost" and the impact of extinction.
Currently living in London, Mr Biswas will uproot his life to exist in the ivory tower from 27 June until 5 August.
His only communication with the outside world will be through his internet blog as he details what life is like in seclusion.
Mr Biswas said: "Well in a way the one thing that is missing from the museum is life - a real live human being.
"Being at top of the this gothic tower is much the same way the brain is at the top of a spinal chord.
"The nature of loss, the cultural memory, I want to question what is important to us and how do we show that we value it?
"I will be in isolation but I see myself performing a social function that is a historically important part of society."
Umm, OK. Apart from living out our fantasies of living in a museum (my personal dream is to have a sleepover in the Great Bed of Ware at the V&A), the Biblical timescale, and perhaps echoing the Romantic notion of the counter-cultural hermit, I don't really see the point of this. I especially love that the museum spokesperson totally missed the point, too:
"By documenting his existence in isolation through blogging and webcam we hope that he will become the museum's ultimate exhibit."
Yes, because museums are zoos. *eyeroll* My other favourite part is that the BBC felt that the appropriate related links would be the Greater Manchester Fire and Rescue Service and the Fire Brigades Union. LOL!
But perhaps we should follow the blog/webcam to see how it goes.
