Philhamonic Society of Bethlehem PSB 95 is a folder with manuscript parts bearing this title information: Ihrer war viel tausendmal tausend — Das Lamm, das geschlachtet ist p. … di Hendel. Who is Hendel? A check of the WorldCat database, the Library of Congress authority file and the RISM OPAC did not provide any clues.
Searching RISM by musical incipit did reveal the identity of the work and the composer. The musical incipits matched George Frederic Handel’s Coronation Anthem, no. 1, Zadok the priest.
This is a case of contrafactum where the Moravians used Handel’s music and applied another text. Oh, yes, someone used a phonetic spelling of Handel’s name.
