He talked incessantly, discussing each detail and following the lines of the drawing with a flabby white finger, covered with hairs on the first joint and ending in a polished, pointed nail, a little livid like the nail of an ape. His voice grated hideously on Sperelli's ear.

'This Dutch edition of Petronius is magnificent. And here is the Erotopœgnion printed in Paris, 1798. Do you know the poem attributed to John Wilkes, An Essay on Women? This is an edition of 1763.'

The collection was very complete. It comprised all the most infamous, the most refinedly sensual works that the human mind has produced in the course of centuries to serve as a commentary to the ancient hymn in honour of the god of Lampsacus, Salve! Sancte pater.

The collector took the books down from their shelves and showed them in turn to his 'young friend,' never pausing in his discourse. His hands grew caressing as he touched each volume bound in priceless leather or material. A subtle smile played continually round his lips, and a gleam as of madness flashed from time to time into his eyes.

'I also possess a first edition of the Epigrams of Martial—the Venice one, printed by Windelin of Speyer, in folio. This is it. The clasps are by a master hand.'

Sperelli listened and looked in a sort of stupor that changed by degrees into horror and distress. His eyes were continually drawn to a portrait of Elena hanging on the wall against the red damask background.

'That is Elena's portrait by Frederick Leighton. But now, look at this! The frontispiece, the headings, the initial letters, the marginal ornaments combine all that is most perfect in the matter of erotic iconography. Look at the clasps!'

The binding was exquisite. Shark-skin, wrinkled and rough as that which surrounds the hilts of Japanese sabres covered the sides and back; the clasps and bosses, of richly silvered bronze, were chased with consummate elegance, and were worthy to rank with the best work of the sixteenth century.

'The artist, Francis Redgrave, died in a lunatic asylum. He was a young genius of great promise. I have all his studies. I will show them to you.'

The collector warmed to his subject. He went away to fetch the portfolio from the next room. His gait was somewhat jerky and uncertain, like that of a man who already carries in his system the germ of paralysis, the first touch of spinal disease; his body remained rigid without following the movement of his limbs, like the body of an automaton.
