Natural History and Natural Philosophy

Although the Heiligmesse it sometimes referred to as the first of the six masses written by Haydn between 1796 and 1802, it is now believed to have been preceded by the Missa in tempore belli , which indeed stands as No. 1 in Haydn's own catalogue. The Heiligmesse owes its title to the fact that in the Sanctus Haydn has introduced into the inner parts, sung by the contraltos and tenors, the traditional hymn-tune ' Heilig heilig ' (' Holy, holy ').
