A Reed pen (Greek: κάλαμοι kalamoi; singular κάλαμος kalamos) is a writing implement made by cutting and shaping a single reed straw or length of bamboo. Reed pens with regular features such as a split nib have been found in Ancient Egyptian sites dating from the 4th century BC. Reed pens were used for writing on papyrus, and were the most common writing implement in antiquity. In Mesopotamia and Sumer, reed pens were used by pressing the tips into clay tablets to create written records, using cuneiform.
Reed pens are stiffer than quill pens cut from feathers and do not retain a sharp point for as long. This led to them being replaced by quills. Nevertheless a reed pen can make bold strokes, and it remains an important tool in calligraphy.
To make a reed pen, scribes would take an undamaged piece of reed about 20 cm, and leave the end that would be cut into point in water for some time. This ensured that the pen would not splinter when cut. They crafted a series of cuts that would cut the nib of the pen until it is flat enough and pointed. The pointed end is then cut off, not too far from the point so it can form a squared end suitable for writing. At the end they would start the split, which acts as a primitive ink barrel, from the tip of the nib and lengthen it until it is of the proper length. They made care not to lengthen it extensively, because the pen was at risk of snapping in half. Being skilled at making reed pens was important for early scribes due to low durability of the pen.
Reed pen in ArtEdit
Until the end of the 19th century, most art was commissioned by wealthy patrons or by institutions such as the church. As such, more traditional depictions of accepted themes were both the most popular and widely accepted. During the 19th century social and cultural changes were reflected in literature and art. With this, artists began to explore different ways to express their vision and create their own personal style. Artist Vincent Van Gogh made good use of the strong stroke and accent of the reed pen, combining it with brown ink and graphite, to create a drawing of a different style.
