Another illustration of Pelasgic masonry is found at Delos (Woodcut No. 127), consisting of a roof formed by two arch stones, at a certain angle to one another, similar to the plan adopted in Egypt, and is further interesting as being associated with capitals of pillars formed of the front part of bulls, as in Assyria, pointing again to the intimate connection that existed between Greece and Asia at this early period of the former’s history. [Illustration: 127. Arch at Delos. (From Stuart’s ‘Athens.’)] In all these instances it does not seem to have been so much want of knowledge that led these early builders to adopt the horizontal in preference to the radiating principle, as a conviction of its greater durability, as well, perhaps, as a certain predilection for an ancient mode. In the construction of their walls they adhered, as a mere matter of taste, to forms which they must have known to be inferior to others. In the example, for instance, of a wall in the Peloponnesus (woodcut No. 128), we find the polygonal masonry of an earlier age actually placed upon as perfect a specimen built in regular courses, or what is technically called _ashlar_ work, as any to be found in Greece; and on the other side of the gateway at Assos (Woodcut No. 129) there exists a semicircular arch, shown by the dotted lines, which is constructed horizontally, and could only have been copied from a radiating arch. [Illustration: 128. Wall in Peloponnesus. (From Blouet’s ‘Voyage en Grèce.’)] Their city walls are chiefly remarkable for the size of the blocks of stone used and for the beauty with which their irregular joints and courses are fitted into one another. Like most fortifications, they are generally devoid of ornament, the only architectural features being the openings. These are interesting, as showing the steps by which a peculiar form of masonry was perfected, and which, in after ages, led to important architectural results. [Illustration: 129. Gateway at Assos.
