THE RIDDLE OF NIJMEGEN

A picture hanging in the Town Hall in Nijmegen since 1658 depicts a sitting young lady with an old man lying in her lap; six sons stand nearby, two in red, two in green, and two in white.

The lady says:
Listen to my declaration
The two in red are my father's brothers
The two in green are my mother's brothers
the two in white are my children and I, mother,
Have from these six the father as my husband,
without consanguinity relations forbidding this.

The two sons in red say:
we would hate it would not be known
That our niece was given to our father,
Because she is not our father's niece
What nobody would easily guess.

The two in green say:
It is strange to see in this picture
that he is our natural father and married our niece
But this does not regret us.

The two in white say:
The old man is father of all of us
The lady is mother of both of us
but say how can it be
That our brothers are our mother's uncles.
