 Responding to the landscape and the embedded religious customs of the country people, and urged on by Sérusier's spiritual expositions, Verkade's religious feelings grew.At Huelgoat he became withdrawn and meditative, attending Mass for the first time.After some time at Le Pouldu, he went home to Amsterdam for four months, immersed in Balzac's "Seraphita", and first read through the Credo while listening to Bach's "Mass in B Minor".
