It's possible you might be misremembering the title or artist.
Here are some possibilities:
* "St. Francis in Ecstasy" by Murillo depicts St. Francis in a mystical embrace with Christ. It is housed in the Museo del Prado, Madrid, Spain.
* "The Vision of St. Francis" by Murillo, also known as "St. Francis Receiving the Stigmata," shows St. Francis receiving the stigmata from Christ. This painting is in the Museo di Capodimonte, Naples, Italy.
It's also possible that the painting you're thinking of was created by a different artist or has a different title. If you could provide more information, like a description of the painting or any details you remember, I may be able to help you locate it.
