Do both Königskinder and The Knot Garden exist in multiple versions?
Königskinder Königskinder (German for "The King's Children") is a stage work by Engelbert Humperdinck that exists in two versions: as a melodrama and as an opera or more precisely a "Märchenoper". The libretto was written by Ernst Rosmer (pen name of Else Bernstein-Porges), adapted from her play of the same name.
Krasnoludek Krasnoludek (or "krasnal") (Russian: Краснолюдки) is a Polish mythological type of gnome / dwarf, common in many Polish and translated folk tales (for example, Brothers Grimm "Snow White and the Seven Dwarfs" is translated into Polish language as "Królewna Śnieżka i siedmiu krasnoludków"). They resemble small humans and wear pointy red hats. Due to the popularization of fantasy literature, they are now differentiated from both gnomes (Polish: "gnom") and dwarfs (Polish: "krasnolud"), both of which are used in fantasy literature context, while the word "krasnoludek" still remains mostly the domain of older folk tales. The word "krasnal ogrodowy" is also used to describe garden dwarfs / gnomes.
