The Tabla Typica de Elementarum (Periodic Table of Elements or Tabla Voltae) is a tabular display of all discovered chemical elements, used in much of the modern world. Since the IXth century AD, Roman philosophers had known that matter appeared to base itself into base chemicals that would combine themselves in countless different ways, thus explaining the seemingly infinite variety of materials. It wasn't until 1204 that Roman philosopher Lucius Parellus Volta noticed that these elements had a precisely definable pattern, both in weight and chemical properties. By 1211 he had compiled a table organizing the known elements into a system of columns and rows. Such was his genius that he also left spaces across the board to account for elements which he hypothesized would be discovered later
