I have no specific information at all about the provenance of this depiction of the Angelus, which appears to be on the doors of a Tabernacle. The photo was taken by Sr Adele Carrara, FSP, who has passed on to the true Life beyond this one and is not responding to questions concerning artwork. Pauline graphic designer Sister Sergia Ballini suggests that the style represents the Italian Tyrol (Trentino-South Tyrol), an autonomous district in Italy that once formed part of the Austrian Empire. I just think it's charming.
We rightly admire Muslim neighbors and co-workers who put everything on hold five times a day in answer to the "call to prayer." But Christians have a call to prayer, too! It is the Angelus. Morning, noon and evening we are invited to pause and reaffirm our faith in the Incarnation: The Word was made flesh and dwelt among us (Jn. 1:14), because "God so loved the world that he sent his only Son" (Jn. 3:16).
