# Beleriand physical-volume materials

These files are presentation materials for the Beleriand map volume. They are
self-hosted so the static atlas does not depend on a third-party service at
runtime. The mahogany desk shared by the volumes is recorded in the
[shared study-material register](../../../shared/assets/materials/CREDITS.md).

## Star-and-wave engraving

The frame ornament is an original in-project SVG drawing. Its repeated ripple
vocabulary was informed by the public-domain [Undulating Wave Motif](https://www.si.edu/object/undulating-wave-motif%3Achndm_1976-103-73)
held by Cooper Hewitt, Smithsonian Design Museum. The museum record marks the
historic source as CC0. The atlas drawing was simplified and combined with its
existing eight-pointed star rather than reproducing the source image.
