History

The astronomer Johannes Hevel dedicated this constellation to the Polish King Jan III Sobieski, which is why the original name was "Scutum Sobiescii". It was the king who freed the city of Vienna from the Turkish besiegers in 1683 at the Battle of Kahlenberg, thus preventing the expansion of the Ottoman Empire in Europe. In addition, he was a strong supporter of astronomy and Hevel himself.
