Quill is a pen made from a flight feather of a large bird, most often a goose. Quills were used as instruments for writing with ink before the metal dip pen, the fountain pen, and eventually the ballpoint pen came into use. The shaft of the feather acts as an ink reservoir, and ink flows to the tip by capillary action. Quill pens were used in medieval times to write on parchment or paper.
The writing instrument that dominated for the longest period in history (over one-thousand years) was the quill pen. Introduced around 700 A.D., the quill is a pen made from a bird feather. The strongest quills were those taken from living birds in the spring from the five outer left wing feathers. The left wing was favored because the feathers curved outward and away when used by a right-handed writer. Goose feathers were most common; swan feathers were of a premium grade being scarcer and more expensive. For making fine lines, crow feathers were the best, and then came the feathers of the eagle, owl, hawk and turkey.
Quill pens lasted for only a week before it was necessary to replace them. There were other disadvantages associated with their use, including a lengthy preparation time. The early European writing parchments made from animal skins, required much scraping and cleaning. A lead and a ruler made margins. To sharpen the quill, the writer needed a special knife (origins of the term "pen-knife".) Beneath the writer's high-top desk was a coal stove, used to dry the ink as fast as possible.
