I could find little information about this piece of art located near the Civic Centre in Cape Town. The piece has no inscription and there's little information on the Web.
What I could find out is that the work was commissioned from the renowned South African artist, Edoardo Villa, in 1981. What's interesting is that in 1981 the National Party won a majority of the seats in government, 131 of the 165 seats. I wonder if the work was commissioned to commemorate this event?
