A zoomed-in view of the Allegro painting. On the right there is a pyramid with a glowing sphere at the tip and three palm trees in front. To the left there is another pyramid, a cone with a glowing spike, then a kneeling man with his head on the ground - the main theme of this sonata. For a long time this painting was missing: in 1910, secretary to the Russian mission to the Netherlands, Pavel Konstantinovich Poustoshkin, acquired “Andante” of the “Sonata of the Pyramids” from an exhibition of M. K. Čiurlionis' work hosted by the Apollon Journal. In 1913, Poustoshkin took the painting along to the Hague. Even though in 1928 the location of the painting was discovered, the price was too big for the museum to pay and the painting was left in Hague with no information about its future.
In 2007, P. Poustoshkin's grandson, who lived in the Hague, reacted to an article “Čiurlionis, still unknown” (by N. Adomavičienė and V. Kavaliauskaitė-Laukaitienė in the journal "Lithuania in the World") and confirmed that the painting purchased by his grandfather was in his possession. After a long correspondence with P. Poustoshkin and with the help of FlyLAL airlines as well as the employees of the Lithuanian embassy in Holland, Čiurlionis' painting was successfully delivered to the M.K. Čiurlionis National Museum of Art.
