Taurus Poniatovii, Poniatowski's bull:

A modern constellation created in 1777 by the Abbe Poczobut of Wilna. He created it in order to honor the king of Poland, Stanislaus Poniatowski. The constellation is made up of stars found in Ophiuchus, the serpent-bearer, and Aquila, the eagle. The stars that were taken from Ophiuchus bear a resemblance to the v-shaped groups of stars (the Hyades) that make up the face of Taurus, the bull. Prior to Taurus Poniatovii, some of these stars were part of the obsolete constellation of the River Tigris. However, both of these constellations are no longer recognized by astronomers, with their stars once again returning to Ophiuchus and Aquila.
