He began at sunset the second day to discover the extent of the besieged quarter and sound every point for the strength of its particular blockade. He found that the Nazarene portion of Rhacotis stretched from the landings of the bay inland to a series of granaries where Rhacotis, in its smaller days, had built receptacles for the wheat which the rustics brought for shipping. To the west it ended against a stockade for cattle, upon which mounted sentries could overlook a great deal of the quarter. To the east, the limit was a compact row of well-built houses, remnants of the Egyptian aristocratic portion in Alexander's time. The streets intersecting the row and leading into pagan Rhacotis were each closed by a sentry. After his investigations, Marsyas felt that here was the weakest spot in the siege. Central in the row was a tall structure, with ruined clay pylons, blank of wall and, except for supporting beams, roofless. It had been a temple, but was now a dwelling, a veritable warren since the Nazarenes were all driven to occupy a portion which could shelter only a fifth of the number comfortably. Upon this structure, Marsyas' eye rested. Either it would be closely watched from without or not at all. It depended upon the features of the wall fronting on the street at the rear, in which the sentries were posted. For once he blessed a Nazarene night-gathering, when he saw family after family emerge from the tunnel-like doors of the temple-house and proceed silently toward the meeting of their brethren in the street below. A long time after the last emerged and disappeared into the dark, Marsyas crossed to the doors and knocked. For a moment after his first trial, he listened lest there be an answer. He knocked more loudly a second time, and, after the third, he opened the unlocked doors, and, putting in his head, called. The heated interior was totally dark and silent. He stepped in and closed the doors behind him. When at last his eyes became accustomed to the darkness, he saw that he was in a single immense chamber; the entire interior of the old temple was unbroken by partition of any kind. Above him, he saw the crossing of great palm-trunks, bracing the walls, and over them the blue arch of the night. At the rear, the starlight showed him the wall abutting the street of the sentries. It was absolutely blank and fully thirty feet in height.
