(From De Caumont's "Abécédaire.")] A splendid mosaic labyrinth of Roman times was found some forty or fifty years ago on a family tomb in the ancient necropolis of Susa, Tunis (_Hadrumetum_). It was afterwards destroyed by looters, but a careful drawing of it was fortunately made on its first discovery (Fig. 37). The whole mosaic measured about seventeen feet by ten, and contained a very finely executed labyrinth of four paths, like the Harpham and Caerleon examples mentioned above, the central space being occupied by the Minotaur, who is shown in an attitude of defeat. Sailing towards the labyrinth was a boat containing figures which presumably represented Theseus and his companions. The design was accompanied by the words "HIC INCLUSUS VITAM PERDIT." [Illustration: FIG. 37.--Mosaic at Susa, Tunis. (C. R. Acad. Inscriptions, Paris.)] Another well-preserved mosaic of this character was discovered in 1884 at Brindisi, and placed in the municipal museum of that town. It measures 17 ft. by 10 ft. 6 in., and shows within a square labyrinth Theseus in the act of clubbing the Minotaur, who has fallen on his knees. Around the labyrinth are various perches with birds thereon, perhaps in allusion to the automatic birds reputed to have been made by Daedalus (_cf._ Fig. 36). We shall examine other mosaic and pavement labyrinths when we come to consider the question of the use of this symbol by the Church. Apart from the designs on Knossian coins, Greek art does not appear to have left us any definite representations of the labyrinths, although with the Romans, who acquired the idea at a later date, it was a favourite _motif_. We cannot, however, ignore the suggestion that has been made that certain structures discovered in the ruins of Tiryns and Epidaurus, two cities in that part of ancient Greece known as the Argolid, are architectural labyrinths, used for ritual purposes. The foundations of the _tholos_, or rotunda, of the sanctuary of Aesculapius at Epidaurus, which was excavated by P. Kabbadias, Director of the Greek Archaeological Society, in the 'eighties, do certainly suggest something of the kind. They consist of concentric circular walls, the three innermost being connected by a radial wall, separated by narrow spaces which intercommunicate by an opening or doorway in each wall, forming in plan a figure somewhat in the style of the "Pigs in Clover" toy mentioned in a later chapter. When the peculiar nature of the upper part of the building is considered, however, it seems very reasonable to suppose that these walls, with their passages, were designed only with a view to the requirements of the superstructure which they had to support.
