Sebastiaen Vrancx, Sebastiaan Vrancx or Sebastian Vranckx was a Flemish Baroque painter, draughtsman and designer of prints who is mainly known for his battle scenes, a genre that he pioneered in Netherlandish painting. He also created landscapes with mythological and allegorical scenes, scenes with robbers, village scenes and celebrations in cities. He was a gifted figure painter who was regularly invited to paint the staffage in compositions of fellow painters. As an active member of a local chamber of rhetoric, he wrote comedies and a number of poems. He was further captain of the Antwerp civil militia schutterij.

The Violieren was a chamber of rhetoric that dates back to the 15th century in Antwerp, when it was a social drama society with close links to the Guild of Saint Luke. It was one of three drama guilds in the city, the other two being the Goudbloem and the Olyftack. In 1660 the Violieren merged with former rival Olyftack, and in 1762 the society was dissolved altogether.
