Montefortino helmets are generally characterized by a conical or round shape with a raised central knob, and a protruding neck guard as well as cheek plates to protect the sides of the head. Other common features include a "rope"-type pattern around the edge, and "pinecone"-type patterning on the crest knob. Note that the classifications are those used by archaeologists, rather than Celts or Romans, who, if they did distinguish among these types, have left no known record of the terms they used.
