Creator: Francis Place after Robert Thacker Three figures using astronomical equipment in the Great Star Room or the Octagon Room, as it is known today, at the Royal Observatory. To the left an observer is using a quadrant to carry out astronomical observations. While a seated figure, on the right, studies the sky through a telescope. Portraits of Charles II, whose support Sir Jonas Moore had crucially secured for the founding of an observatory at Greenwich, and James, Duke of York (later James II), can be seen in the background. This is a reproduction of one of twelve plates showing the Royal Observatory and its equipment that were produced by Francis Place, c. 1676, after drawings by Robert Thacker. The print series was commissioned by Sir Jonas Moore, a mathematician and one of the founders of the Royal Observatory, to commemorate the opening of the Observatory which was established to solve the problem of longitude in navigation.
