[3] Much of his work is inspired by that coastal village where he lived until 1972, when he was forced to move to Ocean View under the Group Areas Act.
He left high school in 1944 and was a dock worker until 1956 when, aged 27, during a three-month holiday to Tesselaarsdal, a small farming village near Caledon in the South West Cape, he began his artistic career.
With assistance from his lifelong friend, poet James Matthews, Clarke held his first solo exhibition in the newsroom of the newspaper The Golden City Post in 1957.
[5] He received six international and six national awards for his art and writing, and had more than 70 solo exhibitions since 1957 in South Africa, Nigeria, Kenya, Australia, USA, Norway, Israel, Austria and the UK.
He also had many group shows in South Africa, Yugoslavia, Germany, Brazil, Austria, Italy, USA, Argentina, Norway, Botswana, Japan, Switzerland and France.
