Adenoids apparently were not mentioned in the medical literature until 1867, when Wilhelm Meyer of Copenhagen described them, but there are many examples of the adenoid expression in early portraits. Almost all the Hapsburgs hang their mouths open as if they were afflicted with adenoids as well as with thin noses. A fine early example is the profile woodcut portrait of Ferdinand, Archduke of Austria, made by Erhard Schoen at Geisberg in 1277. Another woodcut attributed to Hans Baldung Grien shows the Emperor Charles V, as a youth; he also apparently had a throat full of adenoid tissue. This portrait is used as the frontispiece to H. Gebweiler's "Libertas Germaniae" (Strasbourg, J. Schott, 1519). Both portraits are reproduced through the courtesy of the Metropolitan Museum of Art.
