Image: A perforated Alesia fibula. The even arch of the bow is clear as is the perforation. Part of the catch at the foot has broken off. (SC Collection)
Image: This top view of the same fibula shows the evenly tapering bow. The chevron perforation and converging line decoration emphasizes the tapering. (SC Collection)
Typology: Demetz IIa; Feugere 21b1; Gustin I2
Dates: c. 60/50 - 10/1 BC
Distribution: Origin in NE Italy. Common in southern Gaul and the eastern Alps
Notes: The bow is not triangular in form and does not taper evenly. Instead, it begins with a wide section, then narrows at right angles, and then has another wide section above the foot. This gives the over-all form of a letter H or an I-beam.
Image: The I-beam or H shape of the bow can be seen in this top view. The head of this example looks more like an Aucissa fibula. (SC Collection)
