Dmytro Stepanovych Bortniansky (Ukrainian: Дмитро Степанович Бортнянський, Dmitro Stepanovych Bortnians?kyi; Russian: Дмитрий Степанович Бортнянский, Dmitrij Stepanovič Bortnjanskij; also referred to as Dmitry or Dmitri Bortnyansky; 1751-1825) was a Ukrainian composer in Imperial Russia. He composed in many different musical styles, including choral compositions in French, Italian, Latin, German, Slavonic and Russian. In 1882, Pyotr Tchaikovsky edited the liturgical works of Bortniansky, which were published in ten volumes. While Dmytro Bortniansky's operas and instrumental compositions are on par with those of the great classical composers, it is his sacred choral work that is performed most often today. This vast body of work remains central not only to understanding 18th century Russian sacred music, but also served as inspiration to his fellow Ukrainian composers in the 19th century.
The tune he wrote for the Latin hymn Tantum Ergo eventually became known in Slavic lands as Коль славен (Kol slaven), in which form it is still sung as a Christmas carol today. The tune was also popular with freemasons. It travelled to English speaking countries and came to be known by the names Russia, St. Petersburg or Wells; in Germany, the song was paired with a text by Gerhard Tersteegen, and became a well-known chorale and traditional closing piece to the military ritual Großer Zapfenstreich (the Ceremonial Tattoo). Prior to the October revolution in 1917, the tune was played by the Moscow Kremlin carillon every day at midday.
James Blish, who novelized many episodes of the original series of Star Trek, noted in one story, Whom Gods Destroy, that Bortniansky's Ich bete an die Macht der Liebe was the theme 'to which all Starfleet Academy classes marched to their graduation.'
