03 The Alphabet 

the first alaphabet was used around 2000BC in ancient egypt during the bronze age it was the representation of the lungage developed by semetic workers around that time, today  most alaphabets have been directly molded from this one for example the greek and phoenician alaphabets.

the proto-canaantine much like it Ancient Egyptian prototype only represents consonants in a system called abjad linknig ever alphabet ever used to phoenician script, the aramatic script adopted as the official script of the persian empire is the bases of all modernised alphabets in asia.

The Greek alpha adoptied phoenician lettering and became the sole source of all europeian lungages

the greek alphabet is also thought to be the first real modern alphabet as it exchanges cosnotants for vowels.

Roman chiselings were used for documentations for a variety of purposes.

The romans also largely developed books and creating informal handwrighting styles
