This is not an analemmatical sundial. It's just a sundial which shows the mean noon by the aid of the eight-shaped analemma. An analemmatical sundial gives the apparent time by means of the azimuth of the sun. Because the azimuth does not clearly give the apparent time, the shadow caster has to be moved in a definite way. - Daniel
