In the full bronze age, called the Second Siculan Period, burial in rock-tombs still remained the rule. The tomb-form had developed considerably. The circular type was still usual, though beside it a rectangular form was fast coming into favour. The main chamber often had side-niches, and was usually preceded by a corridor which sometimes passed through an antechamber. Occasionally we find an elaborate open-air court outside the facade of the tomb, built very much after the megalithic style. Large vertical surfaces of rock were carefully sought after for tombs, and the almost inaccessible cliffs of Pantalica and Cassibile are literally honeycombed with them. Where such surfaces of rock were unobtainable a vertical shaft was sunk in the level rock and a chamber was opened off the bottom of it. The tradition of the banquet of the dead is still kept up, but the number of the skeletons in each tomb steadily decreases. The sitting posture is still frequent, though occasionally the body lies flat on one side with the legs slightly contracted. Flint is now rare, but objects of bronze are plentiful. The local painted pottery has almost entirely given place to simpler yet better wares with occasional Mycenean importations. It is impossible to decide whether this Sicilian civilization ought to be included under the term megalithic. If, as seems probable, the idea of megalithic building was brought to Europe by the immigration of a new race it is possible that a branch of this race entered Sicily. In that case I should prefer to think that they came not at the beginning of the First Siculan Period as we know it, but rather earlier. Certain vases found with neolithic burials in a cave at Villafrati and elsewhere in Sicily resemble the pottery usually found in megalithic tombs; one of them is in fact a bell-shaped cup, a form typical of megalithic pottery. It is thus possible that an immigration of megalithic people into Sicily took place during the stone age, definitely later than the period of the earliest neolithic remains on the island, but earlier than that of such sites as the Castelluccio cemetery. This, however, is and will perhaps remain a mere conjecture, though it is quite possible that there are in the interior of Sicily dolmens which have not yet come to the notice of the archaeologist; in this connection it is worth while to remember that up to five years ago the existence of dolmens in both Sardinia and Malta passed unnoticed.
