Cosmological Maps
Not every map in this collection was built to help someone find their way somewhere. Some were built to answer a different question entirely: what holds the universe together, and where does it all connect? Across cultures with no contact with each other, the answers converge on a strikingly similar shape.
Mount Meru
In Hindu and Buddhist cosmology, Mount Meru stands at the literal centre of the universe — a cosmic axis around which the sun, moon and stars revolve, surrounded by concentric rings of mountains and oceans, with the realms of gods dwelling at its summit and the human world occupying an outer continent. It is not a map meant for navigation; it's a map of cosmic structure, encoding a complete hierarchy of existence in a single symmetrical diagram.
Yggdrasil
Norse cosmology maps its universe through an enormous ash tree, Yggdrasil, whose branches and roots connect the nine worlds of Norse mythology — Asgard, Midgard, and the rest — into a single structure. A serpent gnaws at its roots, an eagle perches in its branches, and a squirrel runs between them carrying messages — a living, populated cosmological diagram rather than a static geography.
A sacred mountain at the centre, or a sacred tree connecting every level — the specific image changes by culture, but the underlying architecture, a vertical axis binding heaven, earth and underworld into one structure, appears again and again.
Cosmas Indicopleustes's Flat Earth
The 6th-century Byzantine monk and former merchant Cosmas Indicopleustes wrote the Christian Topography, rejecting the spherical Earth accepted by most educated contemporaries in favour of a flat, rectangular Earth enclosed within a tabernacle-shaped universe — a model he derived directly from his own literal reading of the Biblical Tabernacle's description. This is a genuinely earnest and sincere piece of theological cartography.
Worth noting clearly: Cosmas was a real historical eccentric holding a minority position even within his own era, not a representative example of typical Byzantine or medieval belief — a useful cross-reference to the broader "medieval flat earth" myth addressed in this collection's Flat Earth page.
When Traditions Blend Together
Modern esoteric illustration sometimes deliberately fuses several of these traditions into a single composite image. The cover art of Manly P. Hall's 1928 encyclopedia The Secret Teachings of All Ages, illustrated by J. Augustus Knapp, depicts a floating disc bearing a mountain topped by a radiant city — echoing Mount Meru — encircled by a tree whose canopy and roots recall Yggdrasil, connected by a rainbow bridge reminiscent of the Norse Bifröst. No single tradition is copied directly; instead, several independent cosmological "maps" are consciously synthesised into one image, fittingly mirroring the book's own stated ambition to distill "the secret teachings of all ages" into a single work.
