In the morning this light is of luminous and transparent shining, which the curves of the vaults send back all along the hall. Victor Hugo (Le Rhin, ... Hachette, 1876, I. iii. pp. 123-131) describes this ... 'Le phénomène de la grotto d'azur s'accomplit dans le souterrain de Chillon, et le lac de Genève n'y réussit pas moins bien que la Méditerranée.' During the afternoon the hall assumes a much deeper and warmer colouring, and the blue transparency of the morning disappears; but at eventide, after the sun has set behind the Jura, the scene changes to the deep glow of fire ..."—Guide to the Castle of Chillon, by A.
