This is after a portrait painted by William Wissing in 1686 of John Cecil at the age of twelve, who later became the Sixth Earl of Exeter, inheriting Burghley House. His father, the Fifth Earl, was an active patron of Wissing. An engraving was made the same year by John Smith, which was copied later by Petrus Schenk. See Hostein, Dutch and Flemish Etchings, Engravings and Woodcuts, 1450-1700, vol. XXV, no.978 where the Schenk engraving is illustrated. It is the Schenk engraving which the Chinese artist appears to have copied. See the plate with this design in the Rijksmuseum, illustrated by D. F. Lunsingh Scheurleer, Chinese Export Porcelain - Chine de Commande, London, 1974, fig. 252 together with an engraving, also in the Museum, as fig. 253. Another plate is illustrated in colour by Hervouët and Bruneau, La Porcelaine des Compagnies des Indes à Décor Occidental, Paris, 1986, p. 71, pl.3.17; and a teabowl and saucer from this service is illustrated by Howard and Ayers, China for the West, London and New York, 1978, vol. I, p. 249, no. 244.
