The Hill O Many Stanes is an area with about 200 upright stones, none more than a metre high. The rows are not parallel, however, and they create a fan-shaped pattern. This arrangement is believed to be a relic of Bronze Age times.
In Megalithic Lunar Observatories (Oxford University Press, 1971) Alexander Thom presented evidence that the stone rows were in effect a Bronze Age lunar observatory, tracking lunar movements over a cycle of 18.6 years. However, more than twenty similar stone rows are now known in Caithness and Sutherland and none of the others has been linked with astronomical observations.
In Britain stone rows of this kind are unknown outside Caithness and Sutherland, but similar rows of much taller stones are found in Brittany, France.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
