Some scholars, notably P.D. Leveto, interpret the cycle as being "Marian", that is, part of the Life of Mary, rather than specifically representing those scenes associated with the Nativity. Evidence for this interpretation is the presence of the rarely depicted scene of the "Trial by Bitter Water".
Certain scholars, particularly P.D. Leveto, believe that the cycle depicts events from the life of Mary, not just those related to the Nativity. This view is supported by the inclusion of a rare depiction of the "Trial by Bitter Water" scene.
