                                Exterior scene showing a front view of the 7 foot equatorial sextant with a telescopic sight designed for the old Royal Observatory by John Flamsteed (1646-1719) the first Astronomer Royal. The instrument is on an observing platform which includes writing equipment and below, a clock.
Plate 4 (right half detail) from Ichnographia speculae Regiae Grenovici exquisite facta (London, 1676) a series of engravings commissioned by Sir Jonas Moore, the leading force in the construction and equipping of the original Royal Greenwich Observatory. The plate bears the inscription: “Facies Sextantis Anterior 7 ped: Rad:.”
Sir Jonas Moore (1617-1679) mathematician and patron of astronomy was elected a Fellow of the Royal Society in 1674.
