On a flat plane the following lines also will be straight: -azimuth -astrological houses (system Regiomontanus) -italian hours -babylonic hours -siderial hours -ascendants and descendants -the declination line for declination = 0 (equinoxes) The lines for suntime, azimuth and astrological houses can be read with a shadowline. suntime: style parallel to earthaxis azimuth: vertical 'style' houses: horizontal 'style' The other lines need an index for a shadowpoint to read the dial.
