The naves of these three churches were furnished with Gothic cross vaults at the end of the 15th century providing an ideal surface for frescos of the Biblia pauperum (or people's bible) based on popular stories from the richly illustrated medieval manuscripts of the Old and New Testaments.
The artist can be recognised from his distinctive emblem present in one or more of the frescos in all three churches.
His warm colours ranging from dark red and russet to pastel shades of yellow, green, grey and black are distinctive as are the faces of his figures who all have sleepy eyes whether in scenes of heaven or hell.
In the 16th century, following the Reformation, the frescos were covered with coats of whitewash which hid them from view until quite recently.
The Elmelunde Master's school is also credited with the frescos in churches on the neighbouring island of Falster at Tingsted, Nørre Alslev, Kettinge and Åstrup.
