The only relics of ancient ships which have been found at Zea are some plates of Parian marble representing great eyes. Clearly these were the ship’s eyes which used to be fastened to the bows of ancient Greek vessels. Pollux tells us that the ship’s name was painted beside its eye. Philostratus describes the picture of an Etruscan pirate ship painted blue, with fierce eyes at the prow to frighten the enemy. In a list of missing or unserviceable ships’ furniture, preserved in an inscription, mention is twice made of a broken ship’s eye. Some of the eyes found at Zea show traces of red paint at the back; the paint probably adhered to them from the ships’ sides; for ships’ bows were often painted red. Modern Italian sailors sometimes still paint an eye on the bow of their vessel. In the East, too, every craft owned by a Chinaman, from a sampan up to an English-built screw-steamer, has a pair of eyes painted on the bows, that it may see its way and spy out sunken rocks and other dangers of the deep. Indeed, in all parts of eastern Asia where many Chinese travel, the local steamers, whether owned by Chinese or not, all have eyes; otherwise no Chinaman would travel in them, or send his goods by them. Another famous structure in Piraeus was the arsenal, which formed a necessary adjunct to the docks of the navy. We know from ancient authors that it was built from designs furnished by the architect Zeno, who explained them to the people in a speech which won him a high reputation for eloquence. The building was admired for its elegance, and the Athenians were proud of it. However, it was finally burnt by the Romans under Sulla, and no certain vestiges of it have been as yet discovered. But by an extraordinary piece of good fortune the directions given to the contractor for its construction have been preserved to us. They were discovered in 1882 engraved on a slab of Hymettian marble at the foot of the hill of Munychia, not far from the harbour of Zea. The directions are so full, clear, and precise that we now know Philo’s arsenal from roof to foundation better than any other building of ancient Greece, though not a stone of it has been found. A brief description of the edifice, derived from the inscription, may not be uninteresting.
