Close to nothing
Only on my flight back to Amsterdam I was able to put the Icelandic landscape in some sort of context when I watched the documentary Horizon (original title: Sjóndeildarhringur) about Icelandic painter Georg Guðni (1961 - 2011). Coming of age in the rebellious punk scene of the 80s in 1983 Georg Guðni suddenly turned his attention to the Icelandic landscape, at first painting particular mountains but soon painting non-particular mountains and horizons. He put quite some thought into the act of looking itself.
His death is never mentioned in the documentary, but it seems that he took his own life at 50. The male suicide rate in Iceland is high (21,7 per 100.000 people) compared to the female suicide rate (4,7).
The book Strange Familiar - The Work of Georg Gudni was published by Perceval Press (2005), ISBN 0-9747078-9-9.
