Medium includes graphite. This drawing may bear an artist inscription not visible in this image but previously misread as 'Deartas Moderic'. It shows the Desertas, a chain of three uninhabited rocky islands with an isolated rock stack off the southern end, which lies roughly north to south about 40 km (25 miles) off the south coast of Madeira. If Wyllie is looking from Madeira it is from a very low level with the main island being Deserta Grande to right and Chao the flatter, southern, island of the chain to the left. Bugio, the northern island, has the same irregular profile as Deserta Grande though not as high. For more on the group see PAJ1995 and PAJ2009. The drawing is likely to have been done on one of Wyllie's later-life cruises with steamship companies who invited him as a guest and/or to do work they used for promotional purposes.
