Analysis of a pair of canted vertical dials on the Stadhuis in Gouda, Holland, focusing on a direct east-facing nodus dial. Although the direct south-facing dial shows minor discrepancies with the clock time, the east-facing dial's parallel lines meant to be constant-declination curves are considered seriously suspect and likely the result of bad restoration.
