The art is of the most phenomenal perfection, largely Hellenic in idea, yet strangely individual. It imparts an impression of terrible antiquity, as though it were the remotest rather than the immediate ancestor of Greek art. Nor can I doubt that every detail of this massive product was fashioned from the virgin hillside rock of our planet. It is palpably a part of the valley wall, though how the vast interior was ever excavated I cannot imagine. Perhaps a cavern or series of caverns furnished the nucleus. Neither age nor submersion has corroded the pristine grandeur of this awful fane – for fane indeed it must be – and today after thousands of years it rests untarnished and inviolate in the endless night and silence of an ocean-chasm.

I cannot reckon the number of hours I spent in gazing at the sunken city with its buildings, arches, statues, and bridges, and the colossal temple with its beauty and mystery. Though I knew that death was near, my curiosity was consuming; and I threw the searchlight beam about in eager quest. The shaft of light permitted me to learn many details, but refused to show anything within the gaping door of the rock-hewn temple; and after a time I turned off the current, conscious of the need of conserving power. The rays were now perceptibly dimmer than they had been during the weeks of drifting. And as if sharpened by the coming deprivation of light, my desire to explore the watery secrets grew. I, a German, should be the first to tread those eon-forgotten ways!

I produced and examined a deep-sea diving suit of jointed metal, and experimented with the portable light and air regenerator. Though I should have trouble in managing the double hatches alone, I believed I could overcome all obstacles with my scientific skill and actually walk about the dead city in person.

On August 16 I effected an exit from the U-29, and laboriously made my way through the ruined and mud-choked streets to the ancient river.
