Adriaen Valéry, Latinized Adrianus Valerius, also Adriaan Valerius (b. c. 1570 or 1575 in Middelburg; † January 27, 1625 in Veere, province of Zeeland), was a Dutch poet and collector of ''Geusenlieder'' (poems of peasant and burgher life).
Valerius, who came from an originally French family, was a notary in his main profession and later mayor of Veere. However, he became known as a poet of spiritual and patriotic songs. From 1598 he was a member of the ''Rederijkers¬kamer Missus Scholieren'' in Veere, an association of orators and poets; in 1617 he became chief dean of the chamber. He participated in the ''Zeeusche Nachtegael'', a collection of poems by Zeeland poets published in 1623.
The year after his death, 1626, a number of his songs were published in Haarlem, together with some older Geusenlieder, under the title ''Nederlandtsche Gedenck-Clanck'' ("Dutch Memorial Sounds"). The collection was intended to keep alive the memory of the Geuse resistance against the Spanish (Eighty Years War, 1568-1648). It has a clear anti-Spanish and anti-Catholic tendency. Included are 79 monophonic songs with lute accompaniment (in French tablature[1]) and explanatory historical notes. However, the collection, which also contains the Wilhelmus, soon fell into oblivion until it was rediscovered in the course of the 19th century and in the wake of increasing nationalism.
In the "table of contents" there are not the song beginnings or titles, but the underlying melodies ("Ta-fel van de Stemmen ofte Voysen in desen Boeck begrepen" - table of voices of the tunes contained in this book). The works as such are not given a title; at the beginning, the underlying melody is referred to ("(Op de) Stem" - (On the) voice). This is also found in later editions.
In 1871, 19 pieces were set by Abraham Dirk Loman as piano accompaniment in modern notation and provided with explanations as Oud-Nederlendsche Liederen uit den "Nederlandtschen Gedenck-clanck" ("Old-Dutch Songs from the 'Dutch Memorial Sounds'") published by the Maatschappy tot bevordering der Toonkunst ("Society for the Promotion of the Art of Sound") and the Vereeniging voor Noord-Nederlands Muziekgeschiedenis ("Association for North-Dutch Music History"). Attached was also an abbreviated German translation of the explanations. In a second edition of 1893 without large explanations, only with a longer preface, there were 28 pieces. Independently of this, in 1877 Eduard Kremser published a musical arrangement with quite freely transcribed German texts by Josef Weyl as ''Sechs Altniederländische Volkslieder'' (Old Dutrch Folk Songs). From this collection, Wilt heden nu treden developed its own history in Germany as the "(Old) Dutch Thanksgiving Prayer" (Wir treten zum Beten) and another in the United States with English lyrics by Theodore Baker as ''We gather together''.
In 1901 Karl Budde published a pure translation of the Dutch texts in a series of articles in the magazine ''Die Christliche Welt''. In the same year, together with a musical arrangement by Julius Röntgen, who was living in Amsterdam at the time, he published new German song texts under the title ''XIV Altniederländische Volkslieder'' (XIV Old Dutch Folk Songs), which were based on his translation. He took the line "Wir treten zum Beten" in the song now titled Siegesfeier (Dankgebet is called another work) from Weyl because it had already become firmly established. Otherwise, there is criticism from him of Weyl's free transcription, but praise for the skillfully assembled cycle of six. Budde himself is criticized for his rough text and he cannot really assert himself.
