Le Codex Troano et l'écriture hieratique de l'Amérique centrale
Léon de Rosny's 1878 Paris study of the Maya Troano codex and Central American hieratic writing, published by the Société d'ethnographie for scholars of ethnography and Mayan script. The first picture is a numbered chart of eighteen Maya day and glyph signs in bold black line, and the second is an ornate ceremonial staff head with a scrolled finial, a central jewel and a looping shaft. A designer could take from them a strong system of numbered, compartmented icon grids and the crisp, heavy outline style of nineteenth-century print.
