One method of connecting a pair of paintings is to establish that they are painted on two pieces of fabric originally from the same roll. Rollmate pairings can offer insight into issues of dating, attribution, and artist’s intent. A computational procedure developed and applied over the past decade provides a method for identifying rollmates based on color-coded maps providing full painting coverage of spot thread densities automatically extracted from high resolution images. These weave maps display striped patterns shared by other fabric from the same roll that can serve as a key indicator of rollmate status. This talk introduces the concept of thread count automation for a simple weave and the visualization of the results as weave maps. Display of a variety of discovered matches spanning the 15th through the 19th centuries of Old Master European paintings, and evidence that this approach to rollmate identification applies to early (12th – 13th century) silk paintings, illustrates the breadth of utility of this pioneering effort in computational art history.
