Gotland Grooves
Thousands of stones on the island of
Gotland have been found with curious grooves. These
grooves, and their alignments spanning many miles, may
have been an elaborate lunar and solar timekeeping device,
though there exact use is not known.
Thousands of grooves, scattered on stones throughout the island
of Gotland seem to connect the scattered parts together into a
vast timepiece. Aligned with the sun, moon and stars, the
grooves mark an ancient, human obsession with time and space
over 3000 years ago.
Location: Gotland, Sweden
Latitude 57.64°N
Longitude 18.30°E
Alignments: There are about 3600 known
grooves on stones scattered throughout the island of Gotland.
700 are scored directly into the limestone bedrock, the rest
are found on about 800 stones. The length of the grooves varies
from about 0.5 to 1 meter. They are between 5 cm to 10 cm wide
and 1 cm to 10 cm in depth. The most important feature of the
grooves appears to be in their alignment. A recent study of
1256 grooves showed that they are aligned with certain
positions of the celestial bodies, apparently the sun or the
moon. Most of them are oriented east to
west.
