Following the singularity of childhood comes the pairing of adolescence. COURTSHIP DANCE is made of two spirals, each cut from an Ovoid, the symbol of Life. As in LOVE KNOT I cast the two pieces and mounted them together so that the shapes are reaching out to each other, yearning to touch, and to become one, and form DEPENDENT BEINGS.

This dance image comes from a sight I saw many years ago sitting by a billabong in the Outback of northern Australia when I was a cattle drover on the Fitzroy River stock route. Pairs of giant Brolgas, 5 foot high, would leap into the air, twisting together, bills clacking as they sparred, in a courtship dance.

The blind mathematician Bernard Morin pointed out on his visit to Bangor in 1990 (see The Brehm Model ) that what produces the amazing effect of the work is that despite the fact that the two lunes of each part do not intersect, the two ovoids from which they are taken intersect along an oval curve passing through the little ends of the two eggs, so that eventually the two lunes meet there like two beaks. The structure of the sculpture relies on this missing but invisibly organising intersection curve.

COURTSHIP DANCE is one of the sculptures in Bangor.
