Sepulkas[a] (also sepulcas or scrupts in English translation)[1] are fictional objects found in works The Star Diaries and Observation on the Spot by Stanisław Lem. The nature of the objects, their physical properties, and applications were kept by the author from the protagonist and the readers, creating a mystery. In-universe they were described as "objects used for sepuling".
