6 The bone tools used in the five occupation phases

6.4 Carolingian period

The bone and antler tools from this period resemble those from the Merovingian period. Fibre and skins were processed with bone and antler tools. The inhabitants used combs, astragali and amulets or pendants in ritual or magic, made music with a cattle costa and made an (unfinished) flute out of sheep tibia. One of the inhabitants possessed a little box made from a cattle long bone, perhaps to store a precious object or make-up. A decorated bone plate was presumably a piece of furniture decoration.

The two complete one-sided composite combs from this phase are of type 2 and 3. Type 2 was already known in the Merovingian period. Type 3, with straight, narrow side plates and extended end tooth plates, was presumably introduced at the site during the Carolingian period. It was also found in the Ottonian period. This is the only comb type at the site in which cattle and sheep bone were used (table 3). No two-sided composite combs were found in the Carolingian period.
