Top and perspective views of a graphic representation of the periodic table of chemical elements in the style of space concentric circles in eight planes. This table was originated by G. Haenzel in 1943 and classified by chemist Edward G. Mazurs as Type IIIA4-3 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). A version of this illustration appears as Figure 93 on page 156 of Mazurs' 1957 publication.
