Findings in Turkey - sundial, solar clock made of stone
Similar finds have been made recently in Russia.
Here other stone tools on tracking sunrise in days of solstices and equinoxes have been found out also. Inclined or "polar" hours with the shade index have been found not only a sundial with the index of type of the vertical core, inserted into a chink on a stone near to deepening for water level.
The core directed on a pole of the world, and also a template on which the triangular plates were made, representing a circular plate with concentric ring hole in its geometrical centre. This template was used both as a sundial, and as the index of limits of a corner between points of sunrises in days of terrestrial and summer solstices. And our ancestors possessed similar knowledge during an epoch removed from us on some millenia!
Here the stone from white sandstone in the form of a skull of the huge horse, having a through cone-shaped aperture in which it was possible to observe of the voshodjashche-coming Sun, by the Moon, stars or behind a motionless site of the star sky has been found out.
As a result of the further studying of an observatory it became clear that before an observatory the glory of widely known Stonehendge with its clumsy, driven in the earth huge триглитами grows dull.
The tiny model 40 tons stone telescope, easily turns round vertical, and it is even easier - round a horizontal axis from the slightest pressing by a match tip.
