With their shades delicately painted in watercolour with landscapes or town views and in this instance depicting the Hermitage in St. Petersburg, these early 19th Century 'omrakl' or miracle lamps became highly fashionable at the Imperial Court and among the St. Petersburg elite. Various examples were executed for Tsarskoe Selo, and are illustrated in I. Sychev, Russian Bronze, Moscow, 2003, pp. 127-128. G.K. Loukomski also illustrates four examples from the appartment of Empress Maria Feodorovna in his Mobilier & Décoration des Anciens Palais Impériaux Russes, Paris/Brussels, 1928, Pl. LVIII, figs. 128-131.
