When painters in the workshop of the fifteenth-century artist known as the Master of Osservanza illustrated The Meeting of St. Anthony and St. Paul, they solved the problem of how to TELL A STORY in a single painting by merging a series of episodes into one picture.

Explanation:

The Master of Osservanza was the name given to an Italian painter (later attributed to Sano di Pietro, after many researches) who belonged to the Sienese School in the 1400s.

The painting "The Meeting of St. Anthony and St. Paul" tells the story of the meeting, by representing the journey of the two men, in three different parts, until the moment of the meeting. This is how they created the element of storytelling within the same painting.
