"Hath one yet been named Condottiere for this frontier service?" questioned one of the older senators, among a group of the more important men who had detached themselves from the others and strolled out into the great loggia on the sea façade for a reviving breath of the morning air. "For such an employ there is none like Piero Salin for daring and intrigue; and the assassins may linger long in hiding on the route to Rome."

And so they first remembered Piero in these crowded days and discussed his fault with a degree of leniency that would have been foreign to the traditions of Venice had he not been needed for important secret service.

Meanwhile, Fra Paolo was still the theme among the senators at large in the Council Chamber. "Il miracolo del suo secolo," they called him, as they rehearsed the opinions of the learned men of their age in every field of science.

"It cannot be from knowledge, acquired as all men learn, that he taketh this position in such varied sciences," said the Senator Morosini; "for a life-time doth suffice to few men for such attainment in one field as he hath reached in all. It must be that the marvel of his mind doth hold some central truth which maketh all science cognate."

"Else were he not 'friend and master' to Galileo of Padua."

"And it is told that Acquapendente, who hath been summoned by the Signoria to bestow his skill, hath learned of him some matters which he taught in the medical school of Bologna. The world hath not his equal for learning."

"By the blessed San Marco!" ejaculated one under his breath, who had been idly leaning on the balustrade, as he crossed himself and looked furtively around to note whether he had been overheard.

But the others of the group, keenly alive to danger, had instantly joined him.

"Was this some new intrigue?" "Was the night not already full with horror?" they questioned of each other, thrilled with dread and superstition.

Dawn was growing over the water, and the gray and oily surface of the lagoon was closely dotted with gondolas, distinct and black in the morning twilight; they came sweeping on from San Nicolò and Castello—black and red, breast to breast—gathering impetus as they neared the Piazzetta, in numbers which must have left every traghetto of Venice deserted; Nicolotti and Castellani—allies, since they never had been friends! It was some intrigue of the people, or some favor they had come to ask—to-day, when the Senate might not spare one thought for disorder among the masses!
