A cloud tree!
I will credit this photo as soon as I find the name of the photographer
A wonderful blog Tottenham Clouds – which celebrates the weather and Luke Howard – “Namer of Clouds” who lived in Tottenham and we all think his lovely derelict house here should be turned into a Cloud Museum. They have also posted my two versions of the poems sent to Luke Howard by Goethe – which it is said he threw in the bin since he couldn’t believe that Goethe would write to him! The poems are here.
There is also a great post about Luke Howard here: How The Naming of Clouds Changed the Skies of Art
