Taurus Poniatovii

Taurus Poniatovii (Latin for Poniatowski's bull) was a constellation created by the former rector of Vilnius University, Marcin Odlanicki Poczobutt, in 1777 to honor Stanislaus Poniatowski, King of Poland and Grand Duke of Lithuania.

A depiction of the constellation can be found on the wall of the Vilnius University Astronomical Observatory.

The stars were picked for the resemblance of their arrangement to the Hyades group which form the "head" of Taurus.

Before the definition of Taurus Poniatovii, some of these had been part of the obsolete constellation River Tigris.

[1] The five brightest stars belong to loose open cluster Collinder 359 or Melotte 186.
