|The Annunciation, door carving by Bandele of Osi-Ilorin, 1964.|
Here's a great article from 1995 by Laurel Gasque about nonwestern Christian visual art (at least at that time). In it she gives a good overview of the shift of Christiandom from the west to the east, and how this is reflected in a growing body of Christian visual arts from around the globe.
One especially helpful insight is the paragraph in which she mentions Nathan Corbitt's four classifications of contemporary Christian art, based on its purpose: liturgical art, functional art, professional art and mission art. Gasque writes, "Knowing the intent of the artist and the function (i.e., action) of a particular work of art aids us considerably in accounting for its form and content, even at times its quality." These four categories are helpful also when analyzing indigenous visual art forms, in order to determine their possible application to a Christian context such as evangelism, worship, or discipleship (of an artist, or of others through the use of contextualized art forms).
