The artist transposes a medieval ordeal with characters in clothes of his time. The mouth of truth is a lie detecting test to convict or release the adulteress. Included in the legends of Tristan and Iseult and Merlin, this story was previously used by illustrators including Altdorfer and Lucas van Leyden.
Each character has a role. The woman puts a hand in the mouth of the lion raised on a pedestal to be at her level. She is held at the waist by her supposed lover disguised as a fool. Two men wait to establish the minutes of justice.
The alleged cuckolded husband is on the far right of the picture, opposite to the lion. He is accompanied by two lovely ladies who are his witnesses. At his side, a last character sends a wink of complicity towards the viewer of the painting.
This is not a comic book and the verdict of the lion is not known. The lack of fear in the attitude of the woman tells that she wants to win the ordeal. The scene becomes a funny symbol of feminine cunning.
