Masolino sets both events in the same town although they had actually taken place in different cities and at different times.
Throughout the 19th century and the first decades of the 20th, scholars attributed this fresco to Masaccio, until 1929 when it was re-attributed to Masolino.
Some critics claimed that there were sections painted by Masaccio.
In 1940 it was suggested that Masaccio was responsible for the entire architectural background of the scene, including the figures in the background. This theory was accepted by almost all later scholars.
Since the restoration, now that the pictorial techniques can be clearly distinguished, we can rule out any intervention by Masaccio at all, at any rate in the actual execution.
