2. O Jesu Christ, meins Lebens Licht

« One source claims that the Lituo is a Basso Cornett. Other says that it is in fact simply a natural Corno or hunting Corno (German WaldCorno). If Bach used the term Lituo rather than Corno da caccia, it is because this motet was written for a funeral procession (whence the fact that there is Continuo): indeed it was traditional in ancient Rome to use three instruments of the brass family for funerals – that is to say, cornus, tuba and lituus. Thus, the symbolical reference to Roman antiquity in Bach’s choice of Cornett, Trombone and lituus for this piece is obvious. » from http://www.bach-cantatas.com/Guide/BWV118-Guide.htm
