For a long time, only two parts of the “Sonata of the Pyramids” (“Allegro” and “Scherzo”) were on display at the M. K. Čiurlionis Gallery. The middle piece entitled “Andante” had been purchased by Russian diplomat and collector P. Poustoshkin. With his consent, the painting was displayed in Čiurlionis' posthumous exhibition in Vilnius and Kaunas, and later in Moscow and St. Petersburg in 1911-1912. In a letter written in 1928, he explained to the museum that he had bought the painting in St. Petersburg and brought it to the Hague in 1913. According to a letter written by the Dutch Institute of Art History in 1964, “Andante” was exhibited in Milan (at the Galeria Levante). The later fate of the painting was unknown until 2008, when P. Poustoshkin's grandson, then a resident of the Hague, confirmed that the painting purchased by his grandfather was in his possession. “Andante” was bought and delivered to the National M. K. Čiurlionis Museum of Art.

This series demonstrates a clear move towards decorativeness. The thick and rich layer of tempera is mixed with elements that serve as openwork elements and light horizontal strokes.

The foreground of “Allegro” depicts a peaceful night with fantastical silhouettes – structurally, this corresponds to the exposition. The more distant layer of bridges with stairs is the variation, and the top, much lighter layer of sunlit pyramids makes up the reprise.

In “Scherzo”, Čiurlionis uses the principle of the fugue by arranging several rows of whimsical variations on Egyptian motifs.
