The Bilateral form.—The fibulae with the spring coiled on each side of the central bow came into use about 400 B.C., in the late Iron Age civilization, called the La Tène period, from the site on the Lake of Neufchatel, where the richest finds have been made. Together with the introduction of the double spring, there is a continued elongation of the catch-plate, which is turned up as in No. 366 (fig. 152) and attached to the bow as in No. 367 (fig. 153). Later its structural origin is forgotten, and it becomes a solid framework (No. 368).
