Below the shelf of rock on which the Virgin's bed is laid, Giotto
has, according to the custom of the time, represented another
episode of the scene; two women, very lifelike in action and
expression, are engaged in washing and swaddling the Divine
Infant.
So there you go. There are two Jesuses because that was the custom of the time. The question that now occurs to me is, who are the women? Did Mary have au pairs?
