On we walked until we reached the first of many broader gold-lined chambers where layer after layer of the precious metal had been hammered over crude stone, perhaps mixed with fresco plaster, I couldn’t know, and suddenly the ceilings above us were ablaze with magnificent paintings in the old Byzantine style that had once filled the churches of Constantinople and still filled the churches of Ravenna and San Marco in Venice.

Rows and rows of dark-haired round-faced saints gazed down on us with dark brows and unwavering gravity, clothed in embroidered robes, as we moved deeper and deeper into the underground realm.

At last we emerged on a gallery that wound around the upper part of a vast domed space with the feel of a great plaza. All around us passages opened from this great central place to other parts of the seeming city, while above the dome itself was decorated in brilliant sections of green and blue and gold mosaic swirling with vines and blossoms, bordered in red and gold at the top of the walls.

Grecian columns carved out of the soft rock appeared to hold a structure that was in fact part of the mountain. Everywhere the walls lived and breathed with color and ornament, but there were no Christian saints here. The figures that rose from the floor to gaze at us as we went down the rock-cut stairs were angelic and glorious but devoid of all faith iconography. They might have been celebrated members of our people for all I knew, with their shimmering and perfect faces, and grand robes of crimson or cobalt blue or twinkling silver.

Everywhere I saw mixtures of historical motifs, ribbons of egg-and-dart decoration dividing diamond-shaped panels of multipetaled flowers or dark blue night behind symmetrical stars, or painting so vividly real it seemed a glimpse here and there into a real garden. A great harmony held it all together, and gradually my eyes saw that much that had been done here was ancient and fading, yet other areas were fresh and still smelled of the pigment and plaster recently applied. The whole was a visual wonderland.

The lights. I had not noticed it before but of course all this was seen in a wealth of electric light, streaming from horizontal fixtures tucked everywhere along borders, in corners, and beneath the lower rim of the huge dome. The steady brilliance of electric light came from the many doorways.

We had come to a stop now on the marble tiled floor of this huge piazza-like place. I could feel the fresh air moving around us. It smelled of the night beyond, of water and green things.

From one of the doors came a figure to greet us, a blood drinker who resembled a young woman of perhaps twenty. Oval face, and oval eyes, and a complexion like cream.
