This composite bow cross-section has always puzzled me.
The cross-section shows black horn strips on each side of a light brown block of something else. The cap of sinew and the wrap of birch bark are straightforward to identify but surely the light brown central block is some other material not identified by the museum (image from Metropolitan Museum of Art, identified as c1450 to 1500 in date, possibly south German or Swiss) so are they a timber such as maple, or stag-horn, perhaps used as a scaffold to support the bow while the glue sets, or something else? Any thoughts??
