After the destruction of Athens by the Persians, all the older art-works were thrown on the dustheap (whence we are now extracting them), and we do not hear that anyone in Hellas ever troubled himself about the ruins of Mycenæ or Phaistos for the purpose of ascertaining historical facts. Men read Homer but never thought of excavating the hill of Troy as Schliemann did; for what they wanted was myth, not history. The works of Æschylus and those of the pre-Socratic philosophers were already partially lost in the Hellenistic period. In the West, on the contrary, the piety inherent in and peculiar to the Culture manifested itself, five centuries before Schliemann, in Petrarch—the fine collector of antiquities, coins and manuscripts, the very type of historically- sensitive man, viewing the distant past and scanning the distant prospect (was he not the first to attempt an Alpine peak?), living in his time, yet essentially not of it. The soul of the collector is intelligible only by having regard to his conception of Time. Even more passionate perhaps, though of a different colouring, is the collecting- bent of the Chinese. In China, whoever travels assiduously pursues “old traces” (Ku-tsi) and the untranslatable “Tao,” the basic principle of Chinese existence, derives all its meaning from a deep historical feeling. In the Hellenistic period, objects were indeed collected and displayed everywhere, but they were curiosities of mythological appeal (as described by Pausanias) as to which questions of date or purpose simply did not arise—and this too in the very presence of Egypt, which even by the time of the great Thuthmosis had been transformed into one vast museum of strict tradition. Amongst the Western peoples, it was the Germans who discovered the mechanical _clock_, the dread symbol of the flow of time, and the chimes of countless clock towers that echo day and night over West Europe are perhaps the most wonderful expression of which a historical world- feeling is capable.[8] In the timeless countrysides and cities of the Classical world, we find nothing of the sort. Till the epoch of Pericles, the time of day was estimated merely by the length of shadow, and it was only from that of Aristotle that the word ὥρα received the (Babylonian) significance of “hour”; prior to that there was no exact subdivision of the day. In Babylon and Egypt water-clocks and sun-dials were discovered in the very early stages, yet in Athens it was left to Plato to introduce a practically useful form of clepsydra, and this was merely a minor adjunct of everyday utility which could not have influenced the Classical life-feeling in the smallest degree.
