Description
The diagram at the top is a plan of the building where there are 14 ovens (heated by the dung of camels and buffalos) for hatching eggs on each side of a long passage, ab. Each oven houses layers of ovens. The figure below shows the layout of the upper oven, with two hearths (at de), one to heat itself, and the other to heat the oven below. It is adjoined to neighbouring ovens at bc.
This method of hatching eggs in Cairo was described by John Greaves (1602-1652), a professor of astronomy at Oxford who had travelled to Alexandria, Rhodes and Cairo (1635-1640). Robert Moray presented this at the meeting of the Royal Society on 5 March 1668. It was printed in Philosophical Transactions of the Royal Society, vol. 12, no. 137 (January and February 1678).
The figures are copied from RBO/3/292-93. Another copy can be found at RB/1/20/242.
