MILLBURN, John R. Benjamin Martin and the Development of the Orrery, The British Journal for the History of Science, Vol 6. No 24, 1973. The account is of Benjamin Svetonio. This is a treatise dealing with the standard dials and their furniture, but is a compilation prepared for a projected treatise on dialling. Martin’s attempts were to make the orrery available to everyone, the original instruments being very costly.

MILLBURN, John R. William Stukeley and the Early History of the Orrery, Annals of Science Vol 31, No 6, pp 511-528, 1974. A well-written account of William Stukeley’s interest in the Orrery, the first model which was made by John Rowley for the Earl of Orrery, hence the name. The orrery was intended to replace the two-dimensional representation of the astrolabe and the armillary sphere by three-dimensional representation.
