Plan and perspective views of a graphic representation of the periodic table of chemical elements as a helix wound on two stepwise cylinders. This table was originated by American geologist Benjamin Kendall Emerson (1843-1932) in 1911 and classified by chemist Edward G. Mazurs as Type IIA2-1 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). A version of this illustration appears as Figure 45 on page 120 of Mazurs' 1957 publication.
