Writing systems and who deciphered them by Marco Giannini
This infographic shows a wide collection of writing systems, arranged accordingly to their respective phylogenetic relationships. Lines skirting the outer edge represent existing systems, while those that stop earlier refer to systems that are no longer in use.
These days we are able to read most of the systems and connect them with languages that have been or are still spoken. The few still undeciphered are labeled in black, and those only partially known are labeled in dark grey.
Some systems are linked to the names of the scholars who deciphered them and made them intelligible. and the date they succeeded, some others are linked to the historical figures who created them from the ground up. Known historical connections among different systems cross horizontally the graph in form of subtle coloured lines.
The most important and widespread writing systems, and those from which many child systems branch off, are written in a larger font.
