|This image is a faithful representation of an icon inside the Basilica of Saint Paul Outside the Walls: the author(s) is unknown and the image itself is centuries old. As such it falls in the public domain. See http://www.popechart.com/history.htm for documentation|
The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain, and that claims to the contrary represent an assault on the very concept of a public domain". For details, see Commons:When to use the PD-Art tag.
