The design and accuracy of some observatory instruments of the seventeenth century
Abstract:The graduated arcs of some seventeenth and early eighteenth-century observatory instruments have been examined in order to estimate the accuracy of the angular divisions. In addition, the design of the frameworks supporting the graduated arcs has been studied from existing instruments and from contemporary engravings. The analysis attempts to assess the skills of the craftsman rather than the perspicacity of the astronomer.
