The Temple of Sibyl, Tivoli, with the artist sketching in the foreground

We are grateful to Mr. Alistair Laing for pointing out that the present composition corresponds exactly, but for minor variations in the two figures to that of a similar sized sepia drawing given to Florence Court in 1986 by Prof. Frank Mitchell of Townley Hall, Drogheda. The drawing presented by Prof. Mitchell was signed Del Drago. A more elaborate watercolour of similar size but with several more figures, inscribed 'Antonio del Drago 1790' was sold by Christie's, New York, 15th January 1992, lot 61.
