Bastioned Odin Sapphire

Italian bastionato, fortified-with-bastions — past-participle of bastion, derived from bastia (fortified-tower). As a color modifier, bastioned implies a saturated-and-fortified-and-projecting quality, the deep-rich color of Vauban-period military-fortress star-fort projecting-bastion stone-architecture. Sits at the bold-and-fortified end of the grid, parallel to fortified and buttressed.

Old Norse Óðinn, all-father-of-the-Aesir. As a color modifier, odin implies a one-eyed-and-raven-and-runic-wisdom quality, the visual register of Norse-all-father-Odin-and-Yggdrasil hand-one-eyed-and-raven-and-runic-wisdom Norse-all-father-Odin-and-Yggdrasil-and-Asgard odin-and-one-eyed-and-raven-and-runic-wisdom surfaces under Norse-all-father-Odin-and-Yggdrasil-and-Asgard Hugin-and-Munin-raven-and-Mimir-well runic-wisdom-light. Sits at the modifier-and-myth end of the grid, parallel to thor and freya in usage.

An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
