The Tapestry measures 23 metres tall by 12 metres wide and weighs about a ton. Remarkably it was woven in one continuous piece by hand on a 500 year old loom made from two tree trunks. There are over 900 colours in the design, which was woven from behind in a workshop near Aubusson in France. The Tapestry is made from Australian and French wool which was hand-dyed using water from the local river. The design depicts Christ seated in an almond-shaped aura of light known as a mandorla - often used in medieval art to show Christ as a divine being. The figure of Christ is surrounded by beasts representing the four evangelists - the lion of Mark, the eagle of John, the calf of Luke, and a winged man for Matthew - as well as an image of St. Michael, to whom the Cathedral is dedicated.
