Restoration | Saint John's Cathedral

A baldachin for St. John's Cathedral

While I'm waiting for the stone for the Falcon from Franeker to arrive, the other work, in the meantime, just goes on. Right now I'm working on a sandstone baldachin for St. John's Cathedral in 's-Hertogenbosch. A baldachin is a type of canopy under which the statue of a saint is supposed to stand.

To the first message about this restoration.

a canopy of Portland stone that I previously cut for St. John's Cathedral. In this case I did carve the stonemasonry work myself
a baldachin for three statues carved in portland stone , that I carved earlier for St. John's Cathedral. In this case I did carve the stonemasonry work myself

Some years ago I participated for twelve years in carving sculpture for this Cathedral, of 1999 to 2010. In that period I carved lots of different things, from statues of saints and shield-bearers, of consoles, gargoyles, crockets, crockets and finials to reliefs and angels. And also two baldachins for the Sacraments chapel.

In the end it will look like this
eventually such a thing will come to look like this

But that was on the other side of the church, and that side is looking very good now. A number of façades are being taken care of now for major repairs, and weathered natural stone is being replaced, including that side crocket I carved recently and now also this baldachin.
Today someone asked me whether I carve such a block myself and if I order the stone as well. That could have been possible, but with such a restoration as this, all of that is split up in several parts. First there is the restoration contractor, who carefully detaches this old block from the surrounding stonemasonry (of course a long trajectory has preceded all of this, but to keep it simple I'll just pass over that). The old block then goes to the designer at the architect's, who will measure it all and recreates it in AutoCad drawings. All the ornaments on it are drawn as little square blocks. From those drawings, profile templates are printed on plastic film at the stonemason's shop, which are used by the stonemason to carve a new squared piece of stone step by step into a baldachin. Only after that it's delivered at my place(or a colleague's of course). That stone, of course, comes out of a mountain, and not as many people seem to think out of a foundry.

That piece of stonemasonry then arrives at my yard and every part where I need to carve the little flowers a stone cube has been left in place. I have to reconstruct (usually in consultation) these flowers along the lines of the old piece , that is, try to find out what it once must have been like, instead of that dripping candle. As soon as I know what it should become, I start carving ornaments again out of all those cubes.

In this case, the suspended flowers are the trickiest part. Five of these protruding little hanging ornaments, have to be made on the underside of the block in this case. Three of those have to be carved in the round and I still don't know how I should go about that. Maybe I'll just hoist up the whole thing and stand beneath it to carve the work on the inside.

The stone for this piece is Udelfanger sandstone. I'm carving in this stone for the first time; usually it's Bentheimer. Every kind of stone has its ad- and disadvantages. I find that Udelfanger is very easy to work in, and easy to make everything very smooth and with a nice finish as well. And that's exactly what they did with it in neo-Gothic times: everything was totally sanded down and elaborated, almost to the point of becoming scary. Frankly I don't always like that. In the time of architect Pierre Cuypers that was the fashion, and once you see too much of that in one place it is a chilly affair. I always get a little bit sick from the interior of for example Castle Haarzuilens. So many details, and everything carved to perfection but without emotions. Brr.

Anyway, this one also requires that it's all defined quite sharply, and for that, Udelfanger is excellent. I'll let you see later what it's become like.

    Polishing

    Polishing is always a labour intensive chore. Especially in this sculpture; there are many corners that I just simply have to do by hand. But it's getting on nicely, just a few pieces at the top. It's just not very visible on the pictures because there is still a blur of stone sludge over it…

    An Artemis with weak ankles

    At the same time as the two sandstone putti, I also received a statue of Diana or Artemis at the end of last year. It turned out to be a casting of the famous sculpture that was made by the Greek sculptor Praxiteles: the Diana of Gabii, of which the original is in the Louvre Museum. The statue was discovered in 1792 discovered in the garden…

    A boulder with house numbers

    I recently received a request if it was possible to make a boulder with house numbers. Of course that's possible! So I went to a garden materials center and bought a heavy boulder of about a meter wide. It could just fit in the back of my little van, because it weighs over 400 kilos. Having a collision would become a problem at that weight….
