This painting was painted on the occasion of the marriage of a wealthy Dutch merchant from Haarlem and his wife, the daughter of the mayor of Haarlem. At the time, it was unusual for a betrothed to be depicted in the painting in the same rough pose and with a smile on her face. His is holding his hand to his chest to show his determination. And the ring on her index finger stands out.
The fluttering of her neck and the shawl on her left arm are quite distinctive.
On the right side, the artist Hals depicts a place that may have been inspired by the Garden of Love, a fictional garden full of love and fidelity that was popular with 17th-century painters. The Garden of Love was often depicted by 17th century painters as an imaginary garden filled with love and fidelity. You see two couples in this image.
They are also sitting under a thistle tree, which symbolizes fidelity. And the curly whiskers of ivy that wrap around the branches between them or crawl on the ground represent devotion, fidelity, and fertility.
