This repeating circle was in all likelihood used by polymath Cornelis Kraijenhoff (1758–1840) for the first large-scale triangulation of the Netherlands (1802–11). The instrument was made by French instrument maker Etienne Lenoir (1744–1832) according to a design by Jean-Charles de Borda (1733–99). For the metre expedition, a similar instrument was used.
