The constellation Scutum was first mentioned in 1690 by the Danzig astronomer Johannes Hevelius in his work Firmamentum Sobiescii. He named it Scutum Sobieskii (Shield of Sobieski) in honor of his King John Sobieski III, who supported him strongly and in memory of the liberation of Vienna from the Turkish siege. [7, 10]
