Warwik require and maintains a high level of authenticity. This implies a required basis of valid historical evidence. For instance, there is a standing rule that members of the group must possess (and wear) clothing which positively belongs to the decades 1460-1480. Similar rules apply to all other equipment we possess. Among the obvious exceptions are the items used for historical talks/lectures given by the group, insofar as they seek to convey a broader impression of developments and the changing fashions and ways of the medieval age.
Within this framework and regardless of our personal area of expertise, the workmanship of most of our equipment is and remain personal interpretations. They are based on our own studies, common research and historical sources. However, nobody knows whether the author of some particular manuscript has been biased, a liar or simply ignorant of the subject matter. Similarly, it can be difficult (if not impossible) to obtain certain historical facts from within Denmark; in such cases we must often turn to sources from e.g. Germany or Burgundy.
Minding all of this, we try to establish an image of the late medieval period which is as accurate as possible. It is composed of all the impressions and source materials which have been available to us.
In this way, we are able to e.g. recreate a dress in line with 1470-1480 A.D. Not as an exact replica, but rather based on hundreds of impressions from other contemporary dresses. Hence we obtain a reliable interpretation of a late 15th century dress. This principle can be extended to all the re-enactment activities offered and used by Warwik.
