John Christopherson (1921 - 1996) is known for his later career as an artist, which only began in 1950, when he met Jacob Epstein and started to visit West End Galleries in London. In 1959 he resigned from the Civil Service and became a full-time painter, known for small townscapes, exhibiting at the Leicester Galleries, the Marjorie Parr Gallery, Agnews and England & Co. His last exhibition was a retrospective held in 1995 at the Woodlands Art Gallery in Blackheath.

Christopherson was an avid letter writer, corresponding with a wide group of dealers and fellow-collectors who shared his interest in art and indeed in jade carvings. He visited the London auction rooms as well as visiting Portobello market regularly on Saturdays and was known to produce his most recent purchase, often a Chinese early jade carving. By 1994 his illness prevented him from visiting central London.

Lot 122. A pale green and russet jade carving of a recumbent ram, Six Dynasties-Song Dynasty, 5.7cm (2 1/4in) long. Estimate £2,000 - 3,000. Sold for £2,500 (€2,943). Photo: Bonhams.

Carved resting upon its tucked-in legs, the hind quarters slightly raised, the head with almond-shaped eyes looking forwards, with long ridged horns curling over the shoulders, the greyish-green stone with dark brown veining. 

Note: Figures of rams have a long history, appearing in the Han and Tang periods in bronze as lamps and in ceramic as tomb figures. The present piece echoes the still and powerful stone figures that line the Spirit Roads of Tang and Song tombs, yet is much more fluid in form and captures a sense of vitality in the fullness of its form. With the top of its head and back accentuated by the dark natural inclusions, these lines that gently run across the stone further enhance the delicate carving of the creature.

Two closely related examples were included in the exhibition 'Chinese Jade Animals', Hong Kong Museum of Art, Hong Kong, 1996, cat. nos 91 and 94; another in the Kirknorton collection is illustrated in Brian Morgan, 'Naturalism and Archaism: Chinese Jades from the Kirknorton Collection', London, 1991, pl. 38; and a fourth carving in the British Museum, London, is published in Jessica Rawson, 'Chinese Jades from the Neolithic to the Qing', London, 1995, pl. 26:11. See also one sold at Christie's, New York, 2nd December 1985, lot 48; and another sold at Christie's, London, 7th December 1984, lot 306.  

The ram is symbolic of peace, prosperity and filial piety. When carved in stone for Spirit Roads, rams represented incorruptibility and stood in lieu of figures of civil officials. It seems likely that jade rams, such as the present one, represented the roles of sheep in daily life as well as embodying their auspicious associations on Spirit Roads.
