Valerius was the son of a French military clerk and notary, François Valéry.
His father had a somewhat prosperous career, and in 1592 obtained a position as Court Scribe to Pieter van Reigersbergh, the Burgemeester (mayor) of the city of Veere.
Valerius’ father liked to play the organ, and bought a small church organ for 24 guilders when a church was pulled down after the liberation of Middelburg in 1575, during the war between the Hapsburg Spanish and the Dutch republicans.
In 1598, Valerius became a the Toll and Customs Controller for Veere. He married the Burgemeester’s daughter in 1605, advanced to Tax Collections and was later appointed to the City Council, and became a notary for the Estates of Zealand.
Valerius belonged to the rederijkerskamer (chamber of eloquent speakers) of Veere, an amateur poets’ society. He wrote mostly religious texts, an uncommon specialty in the rederijkersmovement.
He penned a number of Dutch hymns, many of which are still sung today, collected in his Neder-Landtsche Gedenck-Clanck (Dutch remembrance-tunes). Among other pieces, he is also remembered for his adaptation of Het Wilhelmus, the Dutch national anthem.
