1996 Luciano, p. 32:
Bonheur is never recorded to have been to Scotland, where he would have seen this unusual breed. Rosa Bonheur painted in Scotland, and its seems likely that Isidore would have drawn the idea for this bull either from one of her sketches or from an agricultural show in France. The animal's rich mane and strong modeling make this one of the most successful.
