The water came up to his armpits; he felt that he was sinking; it was only with difficulty that he could move in the depth of ooze which he had now reached. The density, which was his support, was also an obstacle. He still held Marius on high, and with an unheard-of expenditure of force, he advanced still; but he was sinking. He had only his head above the water now and his two arms holding up Marius. In the old paintings of the deluge there is a mother holding her child thus.
He sank still deeper, he turned his face to the rear, to escape the water, and in order that he might be able to breathe; anyone who had seen him in that gloom would have thought that what he beheld was a mask floating on the shadows; he caught a faint glimpse above him of the drooping head and livid face of Marius; he made a desperate effort and launched his foot forward; his foot struck something solid; a point of support. It was high time.
He straightened himself up, and rooted himself upon that point of support with a sort of fury. This produced upon him the effect of the first step in a staircase leading back to life.
The point of support, thus encountered in the mire at the supreme moment, was the beginning of the other watershed of the pavement, which had bent but had not given way, and which had curved under the water like a plank and in a single piece. Well built pavements form a vault and possess this sort of firmness. This fragment of the vaulting, partly submerged, but solid, was a veritable inclined plane, and, once on this plane, he was safe. Jean Valjean mounted this inclined plane and reached the other side of the quagmire.
As he emerged from the water, he came in contact with a stone and fell upon his knees. He reflected that this was but just, and he remained there for some time, with his soul absorbed in words addressed to God.
