...Sydney University, during the talk delivered by Professor Robert Hannah on the evening of Thursday 26th November, 2009.

“The model of the Antikythera mechanism was designed in 1989 by Dr Allan Bromley, who was an Associate Professor in the Basser Department of Computer Science, at the University of Sydney. It demonstrates the complexity of the gears and the dials of the mechanism that manoeuvred the upper cycle of the 19 year calendar, and the lower cycles used to predict solar and lunar eclipses. The recent research of Allan’s collaborator, Michael Wright, has advanced the understanding of the mechanism, beyond that inherent in this model.

The model was made by Frank A Percival, and is on loan from the estate of Dr Allan G Bromley. It has very rarely been put on public display.”
