Bulb of percussion is a term used in archaeology to describe a specific feature found on certain stone tools. It is an important characteristic that helps archaeologists to identify the type of tool and its intended use. In this article, we will explore the definition and meaning of bulb of percussion, its origin, associations, synonyms, antonyms, root words, and example sentences.
Definitions
The bulb of percussion is a distinctive feature found on the striking end of stone tools such as axes, hammers, and chisels. It is a small, rounded protrusion that forms when a stone is struck with another hard object, such as a hammerstone. The bulb of percussion is created by the shock waves that are generated when the two stones collide. It is an important feature because it helps archaeologists to determine the direction and force of the blow that created the tool.
Origin
The term bulb of percussion was first used by French archaeologist Gabriel de Mortillet in the late 19th century. He recognized the importance of this feature in identifying the function of stone tools and developed a system for classifying them based on their shape and size. Since then, the bulb of percussion has become a standard feature in archaeological analysis.
Meaning in different dictionaries
The term bulb of percussion is not commonly found in general dictionaries. However, it is defined in specialized archaeological dictionaries such as the Oxford Dictionary of Archaeology, which describes it as “the small, rounded protuberance on the striking end of a flaked stone tool, resulting from the shock waves generated by the blow that created the tool.”
Associations
The bulb of percussion is closely associated with the process of flintknapping, which is the technique used to create stone tools by striking one stone against another. It is also associated with the study of lithics, which is the scientific analysis of stone tools.
