Bird on Blue from Villa Livia, Buon fresco, 11×8″,2016, by Margaret Keller.
The top image shows the original detail from a portion of the wall of Villa Livia in Rome. See the historical information for details on Villa Livia. Below is my copy. The plaster I used was slightly darker than the original, so the blue color is darker on mine too. See the images showing this process step by step. Also, the sheet Techniques for Traditional Frescoes, along with the sheets Materials for Traditional Frescoes (to be posted soon).
