A Philosopher Lecturing on the Orrery
One person called Wright "a very great and uncommon genius in a peculiar way". The Orrery was painted without payment. Wright expected that Washington Shirley, 5th Earl Ferrers, an amateur astronomer, will buy the painting, because Shirley had his own orrery, and Wright's friend Peter Perez Burdett was staying with him. Figures are considered to be portraits of Burdett and Ferrers. In the picture, Burdett is taking notes and Ferrers is seated with his son next to the orrery. Ferrers purchased the painting for £210, but the 6th Earl sold it at an auction. It is now held by Derby Museum and Art Gallery as its permanent display.
