Tír na nÓg-yan

Category

ink stones (砚yan).

Material

Metamorphosed Pre-cambrian Dalriadan sedimentary rock from the Moray firth, the lid is a different slate material reclaimed from a roofing slate.

Description.

A round inkstone with a pouring spout and purpelish slate lid with pale green inclusions. Tír na nÓg "Land of the Young" is a fabulous island of the western ocean, the earthly paradise of Celtic myth, where the fairy immortals and a few select heroes enjoy perpetual and abundant: good food, good drink, good music, good weather and good love-making never aging or experiencing winter. The green stone inclusions in the slate lid reminded me of islands in a deep sea as seen from above.

Other info

Metamorphic Bedrock formed approximately 505 to 1000 million years ago in the Cambrian and Pre cambrian Periods. Originally sedimentary rocks formed in deep seas. Later altered by low-grade metamorphism. Dalradian sediments were all deeply buried, heated and compressed as a consequence of the Caledonian mountain-building event. Soft sediments were converted to sedimentary rock, then further deformed and metamorphosed so that we now find schists and marbles instead of the original sandstones, mudstones and limestones. As the rocks were squeezed between the converging crustal plates, the rock layers were folded and contorted, and often turned upside down. The resulting fold structures can be seen in many places along the Moray Firth coast. Before 542 million years ago, what part of the earth's surface would become Scotland was in the Southern Hemisphere, the Dalradian sediments were laid down in an expanding Iapetus Ocean on the margins of a continent we now call Laurentia; later in the Ordovician period these Dalradian sediments were deeply buried. compressed and heated.
