Rydberg's Periodic Table in style of Spiral with Four Revolutions

Periodic table in style of spiral with four revolutions circa 1913 (Original design) and 1957 (Date attributed to slide).

This table was originated by Swedish physicist Johannes Rydberg (1854-1919) in 1913 and classified by chemist Edward G. Mazurs as Type IIIB2-1 in his seminal work Types of Graphic Representation of the Periodic System of Chemical Elements (1957). The lower version of the table appears as Figure 63 on page 132 of Mazurs' 1957 publication.
