Two violins in my workshop this week suggest a topic of study that was addressed recently by the membership of the American Federation of Violin and Bow Makers. Lectures and a collection of instruments for study at the biannual meeting (this year in New Orleans) centered on the influence of the Amati family of makers (17th century), of Cremona, Italy, on contemporary and subsequent makers throughout Europe. Think population centers and European trade routes c. 1700 and one can begin to imagine how instruments may have moved around along with other goods. It’s become clear that the early Amati models not only made the journey, but were so highly regarded that violin makers throughout Europe copied them.
The first is a violin made by Andrea Guarneri in 1686. I believe it is generally accepted that A. Guarneri, patriarch of the Guarneri family of makers, probably studied first in the workshop of Giralomo and Antonio Amati and then later, in Nicolo Amati’s shop (nephew of G and A). It’s also possible that Antonio Stradivari studied with him there. In any case, it’s obvious that the work of Andrea Guarneri would show the influence of the Amati shop. In the example that happens to be in my shop now, probably the most striking similarity, is the classic geometrically derived model, and the shape of the arching. I had the additional fortune this week of seeing a violin by AG’s eldest, Peter Guarneri of Mantua. Very similar arching, but with a broader, longer, more robust outline. I think the axiom that is evident here (and is true for modern makers as well) is that the best makers do not work in isolation, but build upon the ideas of their predecessors, and even their contemporaries.
So Andrea Guarneri was a local boy working in or near the Amati shop. That all makes sense. But what is more amazing to me is that 1179km away, by modern standards thank you googlemaps, and 50-60 years later, we have Peter Rombouts in Amsterdam making an instrument with an Amati influence. Now Mr. Rombouts married the lovely daughter of violin maker Hendrick Jacobs, whose work was also influenced by the Amatis. Did they have a client in common with a superb example worth studying? Were they “following the money” and answering a demand for Cremonese modeled instruments? Did they recognize an efficacious development in design and tone and seize the opportunity to advance their own work??
Who knows?
For the sake of reference, I’ve dug up a few shots of a 1656 Nicolo Amati violin that I see fairly regularly. It’s a lovely instrument, exquisitely crafted with all the delicacy one expects from this maker. See the photo at the left and then compare it to this Peter Rombouts from Amsterdam, early 1700’s, on the right.
It’s so hard ( for me) to get effective photos of archings, so here are the ff holes. There are obvious differences, but I hope the similarities in geometry and placement will be evident. If you imagine the “eyes” on the Rombouts enlarged, you come pretty close to the Amati.
Again, a detail in the back corners. The Rombouts corner is quite worn, but still elongated like the Amati example on top. So not Strad.

The Rombouts is having some extensive work done in my shop, which provides a segue into one reason I care about any of this stuff.
As I approach the end of this particular restoration project, I am faced with the possibility of rebuilding some badly worn top corners. The back corners are somewhat worn, but overall, beautifully intact. However, the top corners, only two of which are original, are terribly worn down. Obviously, the back corners will be my primary reference, but as I am trying to recreate the missing bits, having a sense of the larger picture and understanding more about the derivation of Rombouts’ design can only help me.

Above, one can see that the top edges have been fully doubled. I have made a tracing of the back C bout/ corners and shaped the new top wood to this outline. Below, I have cut away the worn wood around the purfling (which is whale baleen by the way, in the manner of this Dutch maker) and added new wood to the outline. From here, I will do some further shaping to emulate an appropriate wear pattern. The “new ” wood I’ve used is very old and heavily oxidised, so hopefully it will require a minimum of retouching to match.
