David worked extensively on drawings to develop the theme and composition, including many hours of life-drawing studies. The materials and techniques were quite original and had to be developed through innovation and experiment. Even information on Egyptian relief carving was assimilated. The Quarry environment of the time seems to have been particularly alive with talent and there was input from other artists also.

On a test wall David developed the carving techniques. He experimented with wax resins combined with clay, oxides and metallic pigments until satisfied that he had the media that would withstand the elements.

The design was then transferred onto the wall and he began carving, then plastering and sanding. The pigment sealers were applied and then an inlay of paua shells and mother of pearl became the eyes.

Finally, after about five months work, on 29/7/88 a dawn blessing was held and the project was complete.

Now 14 years later, the integrity of David's experimental methods and materials has stood the test of time.
