Orphans 1, one of the Works of Mercy by Frederick Cayley Robinson, 1915. Wellcome Library no. 672831i.
Cayley Robinson is mentioned, in passing and more unpredictably, in the autobiography of the radical campaigner Havelock Ellis (1859-1939), where he appears in a completely different role: as landlord. In 1903 Edith, Mrs Havelock Ellis, "arranged with the artist Cayley Robinson to take his flat in an ancient house on the Quai [de] Bourbon in the Ile Saint Louis in Paris for month of June."  Cayley Robinson had been a student in Paris, and after leaving Florence evidently used a pied-à-terre in that attractive street near the cathedral of Notre Dame (above).
On Thursday 28 July 2011 the auction firm of Chorley's at Cranham, near Cheltenham, will offer for sale a modello (above) by Frederick Cayley Robinson for the Orphans, one of the four paintings in the Wellcome Library . It comes from the accumulated collection of Tony Haynes, a Gloucestershire art-dealer. The modello (lot 359 in the sale) is signed and dated 1914 in the lower left corner, the same place in which the finished version is signed and dated 1915. Measuring 65 x 111 cm., it is on a scale of 1:9 compared with the area of the finished version (199 x 339 cm.).
As might be expected of a modello on this scale, the composition is completely worked out. To work out the composition, Cayley Robinson will have already painted studies on a smaller scale: there is a smaller study for the Orphans, measuring 21.6 x 37.5 cm., i.e. 1:9 again compared with the Haynes modello, or 1:81 compared with the area of the finished version. This small preliminary study in tempera formerly belonged to the parasitologist G.H.F. Nuttall (1862-1937), whose collections of photographic prints and lantern slides, aesthetically rather different from Cayley Robinson, are also in the Wellcome Library (example right: a Kentucky family of "dirt-eaters" with hookworm, Wellcome Library no. 750040i). 
The Haynes modello might have been painted for the approval of the patrons, Edmund Davis and the Governors of the Middlesex Hospital. It is inscribed on the verso in what looks much like the artist's hand, though, oddly, the inscription spells his name wrongly (Caley: left, from Chorley's website). As this composition is for many people their favourite among the four pictures, there must be a fair chance of the modello reaching its lower estimate of £6,000.
