Owing to their large number, gold bracteates should be well suited to form the framework of a style chronology for the Migration Period which is not based on typological development. Where copies from the same die appear in different finds they indicate contemporaneity. The relative time of production of the associated objects in the finds may be judged from the wear on the loops and rims of the bracteates. On the basis of this a sort of stratigraphy may be established in relation to which other objects such as relief brooches may also be placed.
The development of style should then be investigated through an analysis of the motives down to the smallest detail as well as an evaluation of their stylistic content. In both cases precise definitions should be applied. In the process of this work one may distinguish different workshops on the basis of consistent similarities, such as mirror image dies or specific rare details.
