St. Helena Welcomes St. George into Heaven
Franciscan Museum, Dubrovnik (unlabeled)
The title is my hypothesis regarding the two saints. The soldier saint does not have St. George's shield, and the dragon could conceivably refer to St. Theodore. The cross may identify the welcoming personage as Helena, but she does not have that saint's customary crown.
