When Lydgate entered the Yew-tree Walk he saw Mr. Casaubon slowly receding with his hands behind him according to his habit, and his head bent forward. It was a lovely afternoon; the leaves from the lofty limes were falling silently across the sombre evergreens, while the lights and shadows slept side by side: there was no sound but the cawing of the rooks, which to the accustomed ear is a lullaby, or that last solemn lullaby, a dirge. Lydgate, conscious of an energetic frame in its prime, felt some compassion when the figure which he was likely soon to overtake turned round, and in advancing towards him showed more markedly than ever the signs of premature age⁠—the student’s bent shoulders, the emaciated limbs, and the melancholy lines of the mouth. “Poor fellow,” he thought, “some men with his years are like lions; one can tell nothing of their age except that they are full grown.”
