Archive reference number




Landscape view of the horizon as seen from Mount Guajara. Mountain rock is visible in the foregeound, and a shadowy outline of further cliffside is visible in the background. The mountain range appears to sit above the clouds, and the sky is a mixture of bright yellow, orange, and lilac.

Inscribed in ink underneath: 'The cloud horizon Westward from Guajara, showing the summit of Palma above, and the base of Gomera below the cloud.'

From the 'Tenerife Papers of Charles Piazzi Smyth', a scrapbook of watercolours and stereo plates from Smyth's 1856 astronomical expedition to a volcanic mountain range in Tenerife.

This particular watercolour features as the top half of plate XXXII in Smyth's paper 'Astronomical experiment on the peak of teneriffe, carried out under the sanction of the lords commissioners of the admiralty', published in the Philosophical Transactions of the Royal Society, vol. 148, 1858.

Charles Piazzi Smyth (1819-1900) Italian Astronomer was elected a Fellow of the Royal Society in 1857, but resigned in 1874.
