Othmeralia

On this day in 1869 Dmitrii Mendeleev sketched his first draft of the periodic table.  While Mendeleev’s version remains the most common, alternative arrangements include circular, cylindrical, pyramidal, spiral, and triangular layouts.  Indeed, Edward Mazurs chronicled over 140 types in his seminal work, Graphic Representations of the Periodic System over 100 Years! Which one gets your vote?
