POSSIBLE ASTRONOMICAL REFERENCES IN TWO MEGALITHIC BUILDINGS OF ANCIENT LATIUM

Abstract

In the wide area of the ancient Latium Vetus-roughly enclosed within the coast and the Apennines between Rome and Terracina, in Central Italy - there are several examples of town's walls and buildings constructed with the spectacular megalithic technique called polygonal, in which enormous blocks are cut in irregular shapes and perfectly fit together without mortar. In many cases, for instance in Alatri, Arpino, Circei, Norba and Segni, the megalithic size of the blocks and the ingenuity in construction reach the same magnificence and impression of power and pride which characterize the worldwide famous Mycenaean towns of Tiryns and Mycenae, constructed around the XIII century BC. In Italy however, all polygonal walls are currently attributed to the Romans, and dated to the first centuries of the Roman republic (V-III century BC), although for most of these constructions no reliable stratigraphy is available. In the present work, which is part of an ongoing project aiming at a complete study of these buildings, we investigate the possible astronomical references in the planning of two among the most imposing of them, namely the so called Acropolis of Alatri and Circei.
