9, is an opera in four acts written from 1931 to 1936 by the Swedish composer Lars-Erik Larsson; the Swedish-language libretto is by Finnish author and playwright Zacharias Topelius.

There are parallels to the Iliad and Odyssey, and Topelius uses the conflict of cultures between the noble Greeks and the barbaric Nordic countries.

The shepherd's revenge song is inspired by rune singing, and Anemotis's view of Hellas has exotic contours.

[2] Fredrik Pacius used Topelius's story for his fairy-tale singspiel Prinsessan av Cypern (Helsinki, 28 November 1860).

[3] Prinsessan av Cypern was premiered at the Royal Swedish Opera in Stockholm on 29 April 1937 with Hjördis Schymberg and Set Svanholm in leading roles, and the orchestra and chorus conducted by Herbert Sandberg, costumes by Jon-And and choreography by Julian Algo.

The conductor Joakim Unander devised a short orchestral suite Tre Bilder (Three pictures) for a concert broadcast during the composer's centenary.

Tiera and a slave call Lemminkäinen to battle in a neighboring village, and when he learns that Kyllikki has gone to the ship, breaking her promises he throws himself into the fighting after giving Helka his magical hair brush, which will bleed the day he dies.
