I am half sick of shadows (1916) is an oil painting by the English Pre-Raphaelite painter John William Waterhouse. This painting is based on The Lady of Shalott by Alfred Lord Tennyson.
It illustrates the lines:
There she weaves by night and day
A magic web with colours gay.
She has heard a whisper say,
A curse is on her if she stay
To look down to Camelot.
She knows not what the curse may be,
And so she weaveth steadily,
And little other care hath she,
The Lady of Shalott.
