The skomorokhs (Sing. скоморох in Russian, скоморохъ in Old East Slavic, скоморaхъ in Church Slavonic) were medieval East Slavic harlequins, i.e., actors, who could also sing, dance, play musical instruments, and compose most of the scores for their oral/musical and dramatic performances. The etymology of the word is not totally clear. There are hypotheses that the word is derived from the Greek σκώμμαρχος (cf. σκῶμμα, "joke"); from the Italian scaramuccia ("joker", cf. English scaramouch); from the Arabic masẋara; and many others.
