This is a class of monsters which, like the chimera, are assembled from pieces of other beasts or monsters. A great many of the classic monsters of heraldry may be described in this manner: e.g., the griffin, with the forequarters of an eagle and the hindquarters of a lion. But the term usually denotes those monsters with no independent history. They are thus usually blazoned by parts, e.g., “A monster with the forequarters of a dragon, hindquarters of a lion”, or the “cock with the head of a goat” in the arms of von Kockorsch, 1605 [Siebmacher 74].
There are exceptions, such as the Hrassvelg monster, which have been given special names; but this is no longer done, out of pity for the artists.
