Today restoring ancient ‘‘camera obscura sundials’’ by drilling holes in building fac¸ades appears as an overly intrusive intervention in historical architecture. For this reason, our study proposes an innovative, low-cost gnomonic instrument, capable of adapting to any type of relationship between the fac¸ade where the original gnomonic hole was located) and the sundial on the floor. The tool that we have designed allows incoming sunlight to be caught by a reflection system of flat mirrors, appropriately tilted, thus producing a solar ray that exits the instrument with a different inclination. We created new angular relationships between the gnomonic hole and the astronomic data engraved along the sundial in two case studies of hi...
