Purple Forbidden Enclosure · Zǐwēi Yuán

Purple Forbidden Enclosure (Zǐwēi Yuán) is a large organizing framework in traditional Chinese uranography. It covers a circumpolar northern region around the celestial pole, containing many smaller named asterisms rather than functioning as a single connect-the-dots figure.

Chinese great frameworks

History and cultural context

In historical Chinese star catalogues it provided an imperial celestial court centred on the pole, with asterisms representing palace walls, officials and institutions. The framework developed through long textual and observational traditions and its exact contents should be read from a specific historical chart or catalogue.

How Purple Forbidden Enclosure maps the sky

An enclosure is defined by chains of wall asterisms and the many figures within them. Its footprint overlaps several present-day IAU constellations, but those modern boundaries did not exist in the traditional system.

Interesting facts about Purple Forbidden Enclosure

  • In historical Chinese star catalogues it provided an imperial celestial court centred on the pole, with asterisms representing palace walls, officials and institutions.
  • It is commonly located around a circumpolar northern region around the celestial pole, but that comparison does not make it identical to a modern IAU constellation.
  • An enclosure is defined by chains of wall asterisms and the many figures within them.

How it fits the combined catalogue

The directory stores Purple Forbidden Enclosure as one canonical entry and uses badges for membership and overlap, rather than duplicating it under every official constellation it touches.

Research and cultural care

Retain the Chinese name and distinguish the organizing framework from its constituent mansions and asterisms. Avoid presenting modern IAU overlays as exact translations.

A personal connection to the night sky

Name a star while exploring Purple Forbidden Enclosure

Create a symbolic star registration with a certificate and sky coordinates, then use this guide to explore the surrounding sky. Cultural sky traditions do not always follow modern IAU boundaries, so availability is based on the corresponding astronomical region.

Star naming is a symbolic gift service. It does not change scientific names or designations maintained by the IAU.
