The enormous changes that we see in Ruskin, the Ruskin of Herkomer’s portrait, were caused by events which took place between February 14 and April 23, 1878. It was during this period that he experienced his first bout of full-blown insanity. Five more were to follow.
At the top of a blank page in his diary, Ruskin wrote of this period:
“February, — to April — the Dream”
— Wolfgang Kemp, The Desire of My Eyes
