This kind is an analemmatic sundial which is described in several introductory books to sundials. It gives the time by the suns azimuth. Because the solar time is not only depending on the suns azimuth but also on the suns declination (varying seasonally), the gnomon (i.e. the person) has to take a special position within the sundial which is marked e.g. with the firsts of each month.
