Byblos is an ancient Phoenician city along the coast of modern day Lebanon. Its name was the origin of the Greek word "biblion" which means "book", from which derived familiar words such as "bibliography" and "Bible". In short Byblos is nearly synonymous with writing.
Ironically, Byblos was also home to a still poorly understood script employed roughly during the middle of the second millenium BCE. There are only a few short examples of this script, mainly on stone or metal. This script contains roughly one hundreds signs, which agrees with the number of signs necessary for a syllabary.
The following is an example of the Byblos script.
