Old Pens
The appearance of writing instruments is closely on which they recorded with the shape of the font, the substrate and connected to the cultural sense of aesthetics.
To write with cuneiform writing on clay tablets, the Babylonians used a stylus with a triangular tip with which they expressed the characters in soft clay. This led to good readability of the text on the clay. In many places (such as in ancient Egypt ) was written with a write pipe of reeds. The modern Arabic word for pen qalam derived as before from the Latin word calamus ( = reed ).
The Romans used stylus to write on wax tablets. Papyrus from Egypt but also was used. Later quills were used. Suitable bird feathers are usually derived from the wings of geese and ravens. Calligraphers use such springs still. Pencils have been developed in the 16th century and participated in various forms. They are made of wood surrounding a mine which first consisted of lead and silver alloys and later of graphite.
