This painting is displayed to celebrate the eightieth birthday of Derek Hill, British portrait and landscape painter, stage designer and writer. Since the 1930s he has travelled widely, acquiring detailed knowledge of many cultures and traditions. He has had a home in Donegal since 1954 but has continued to live and paint in other regions. In 'Lancashire Slate Quarry' Hill attempts to represent nature truthfully, while at the same time obeying the formal principles of picture-making. Here he places the viewer in a precipitious yet privileged position before this man-made monument, its depth and height suggested by receding planes of tone.
