The Song of Los

I've posted before about the little tidbits the Oxford Handbook of Clinical Medicine contains. A welcome break from the horrors of revising glomerulonephritides was this beautiful picture from William Blake's the Song of Los. It depicts a cloud-borne Los leaning over his hammer, looking down at the sun. The authors of the Oxford Handbook felt this was rather more representative of a 'haemotologist hammering a red cell into shape', based on this quote:
"Every space larger than a red globule of man's blood is visionary, and it is created by the Hammer of Los"
[Los was a mythological character, a fallen god, and his hammer represented creative energy.]
