and in other places a perfect little meadow had grown in the midst of a
hall, or an arcade; for Octavianus Augustus, Tiberius, Vespasian, Titus
and a whole series of prefects, had already carefully removed the finest
of the mosaics from the famous palace of the Ptolemies, and carried them
to Rome or to the provinces, to decorate their town houses or country
villas. In the same way the best of the statues were gone, with which
a few centuries previously the art-loving Lagides had decorated
this residence--besides which they had another, still larger, on the
Bruchiom.

In the midst of a vast marbled hall stood an elegantly-wrought fountain,
connected with the fine aqueduct of the city. A draught of air rushed
through this hall, and in stormy weather switched the water all over the
floor, now robbed of its mosaics, and covered, wherever the foot could
tread, with a thin, dark green, damp and slippery coating of mossy
plants and slime. It was here that Keraunus leaned breathless against
the wall, and, wiping his brow, panted rather than said: "At last, this
is the end!"

The words sounded as if he meant his own end and not that of their
excursion through the palace, and it seemed like a mockery of the man

"Good, then we can begin our re-examination here, at once."

Keraunus did not contradict him, but, as he remembered the number of
stairs to be climbed over again, he looked as if sentence of death had
been passed upon him.

"Is it necessary that I should remain with you during the rest of
your labors, which must be principally directed to details?" asked the
prefect of the architect.

"No," answered Pontius, "provided you will take the trouble to look
at once at my plan, so as to inform yourself on the whole of what I
propose, and to give me full powers to dispose of men and means in each
case as it arises."

"That is granted," said Titianus. "I know that Pontius will not demand a
man or a sesterce more or less than is needed for the purpose."

The architect bowed in silence and Titianus went on.

"But above all things, do you think you can accomplish your task in
eight days and nine nights?"

"Possibly, at a pinch; and if I could only have four days more at my
disposal, most probably."

"Then all that is needed is to delay Hadrian's arrival by four days and
nights."

"Send some interesting people--say the astronomer Ptolemaeus, and
Favorinus, t
