Hi, Katrin!
I have a question about the Lengberg find that looks like a pair of bikini underpants, and I thought, given your areas of expertise, that you might be able to help me with it.
I blogged about that particular item awhile ago, pointing out its resemblance to the ancient Roman subligar which was worn by women, and an anonymous blogger commented that the Lengberg find had been identified as a man's garment. The blogger also claimed that a lot of 15th c German images show men wearing such garments.
The University of Innsbruck's web article on the finds agrees with my anonymous blogger--it identifies the item as a man's garment, and remarks, I believe, that it was found close to a wool fabric scrap believed to have come from a codpiece. Given that the Lengberg finds did not come from graves, I don't think that sort of association, in and of itself, is persuasive evidence. But there may be other evidence I don't know anything about that supports the identification of the garment as male.
Can you point me to any images confirming that men wore such garments? The English and French images with which I am familiar show men wearing briefs that look more like modern Fruit of the Loom briefs, but I'm not very familiar with 15th German miniatures or artwork.
Any suggestions you can make or information you can point me to would be appreciated. Thanks!
