What is the meaning of Seshimori Ishi ?

My sculpture was based on the traditional Japanese sekimori ishi. Here is a photo of one in use in a Japanese garden.

I am interested in visual symbols, particularly ones that may convey multiple meanings.

Sekimori ishi means boundary guard stone. It tells you that a path is closed, but also provdes a convenient handle for moving the stone, so that you can ignore the message. It is not a “Keep Out” sign, but is more of a polite suggestion. The tea master Rikyu is said to have used it as a metaphor for “stay on the right path in life”.

This is a symbol that contains its opposite, much like Nabuo Sekine’s Mono Ha sculpture, Phase-Mother Earth at Suma Rikyu Park.

The idea behind the sculpture was to include multiple opposites, in addition to this implied restriction and permission of the object itself. The boulder is natural and unworked, while the iron is man made and cast. The upright stone is male, but the rounded form with the ring is female. The boulder is positive space, the iron encloses negative space. Yin and yang. Hot iron and cold stone.

The design of the iron is based on my youth in Pittsburgh. This engraving shows my neighborhood a century before I was born. I grew up playing on coal mine dumps, and there were coal mines under my neighborhood. I got to see lots of early ironwork, some of it in the form of machinery that still worked for decades. My neighborhood was on the third hill from the river.

You can view this sculpture as my desire for you to stay on the right path. As it mimics the aesthetics of 19th and early 20th century iron, it can also mean that you should avoid the excesses of 19th century industrialization and capitalism, or not, as you wish.

Other Interpretations

Other viewers have other ideas of what the sculpture means. Possibly due to Mylie Cyrus, some view it as a wrecking ball. I deny this, and the design was started before her video. On the other hand, if you make a wrecking ball video or photo using this sculpture, please send me a copy.

Several people have seen this as a kraken, devouring the rock. Although octopi have eight tentacles, and squid have ten, I can see this visually.

Uther people have suggested that this looks like an ancient anchor. Anchors are a traditional symbol of hope, so I enjoyed this idea. After the sculpture was made, I found this large buoy anchor in Latvia.

Carol Johnson has written that this reminds her of a bell. I have cast bells, although they have been much smaller than this. I would not want to try to ring it. What is the sound of one boulder ringing?

Making Sekimori Ishi at Pedvale

My plans changed a bit from the initial proposal, which was to cast iron directly around the granite.  See my previous post about cultural resource management, and choosing the stone.   I could not have completed this sculpture without the help of my assistants, Sutton Demlong and Justin Playl.  Both were highly recommended by Tamsie Ringler.

Sekimori Ishi

Sekimori Ishi

This is my sculpture for the Iron Stone Symposium and the 7th International Conference on Contemporary Cast Iron Art, completed in June, 2014. It is on permanent display at the Pedvale Open Air Art Museum in Pedvale, Talsu Novads, Latvia.

Design of Sekimori Ishi for Pedvale

This is a design for Sekimori Ishi, to allow construction on-site at Pedvale. The sculpture consists of an unmodified granite boulder, about 4 feet tall, (1.2 meters) and 5 cast iron pieces which are bolted together. This will be permanently sited outdoors at Pedvale Open Air Museum. The proposed sculpture is an iron and granite representation of a sekimori-ishi, which is a feature of many Japanese gardens.. This sculpture was inspired by Nabuo Sekine and the Mono Ha movement. Mono Ha is a Japanese art movement related to Land Art, which encouraged the production of objects, usually of natural materials. If you grow up in Pittsburgh, cast iron is a natural material.

 

The sculpture is based on the traditional sekimori ishi, as used in Japanese gardens. The term means “boundary guard stone”. As shown below, this is a small boulder, tied with garden twine, which forms a handle. Sometimes, this is a metaphorical warning to “stay on the right path”. At other times, it refers to a danger or unpleasantness along that branch of the path. It can also be a request for privacy. This is a polite request, that can be easily ignored by stepping over the stone or moving it.

This is the original maquette, solid aluminum cast in one piece around a granite stone. The full size sculpture will mimic this visually, but the “arms” will be hollow, and will not join at the bottom of the stone. The “ring” has been slightly modified, and rotated 45 degrees. It should appear possible to pick up the sculpture with the lifting ring on the top, but it will actually be lifted with a sling, and the iron pieces are not actually used for lifting. The idea is to give the Japanese symbol the style of 19th century industrial iron. This could be interpreted as a post-industrial comment on the abuses of 19th century industrialization.

The arms will be made at Pedvale from gray cast iron. They will have an open rectangular cross section, with the open end facing the boulder, which is approximately 4 foot tall. (1.2 meters).
Dimensions of the arms are D=6 inches (15 cm), B= 3 inches (7.5 cm) t=1/2 to 5/8 inches (1 to 2 cm), depending on material available to make the casting patterns.

There are 4 arms, at right angles to each other. For identification, label them north, east, south, and west, like a compass. They do not need to be oriented to the compass direction when the sculpture is sited.

The arms will be curved to fit the boulder, and have squared-off ends. They will be bolted to the boulder through a hole in each end. The bolts, made of threaded steel rod, will be anchored in the boulder using a commercial, long set up time epoxy.

The lifting ring has been re-designed to have a round, 12 inch diameter circular hole. (20 cm in diameter). This should be large enough, so that viewers can not get their heads stuck in the sculpture.

The plate will be bolted to the 4 arms with 1/2 inch diameter threaded rod,or a metric equivalent. This will pass through the upper end of the arm, then the cross shaped part of the lifting ring, them into an epoxy-filled hole in the boulder. Loc-tite or something similar will be used to prevent the nuts from being removed.

The arms will slide over the protruding ends of the cross shaped lower piece of the ring assembly, in a mortise and tennon joint. There are two threaded rods holding each arm, one at each end. The rods are placed and set in epoxy after the lifting ring and the arms are placed and fitted to the boulder.

As the arms do not actually cross at the bottom, the first few inches of the sculpture will be buried in gravel, to hide the lower end. This should make it appear that the arms cross under the boulder. If possible, I would like to use very small crushed limestone, and ram it into place. This may be mixed with local clay, if it is available. I have see lime-clay-flint foundations over 1000 years old in Winchester, England.

As a final addition, I would like to bolt a large piece of cast aluminum to at least one of the lower arm ends to act as a sacrificial anode. This can be any locally acquired scrap aluminum. Since aluminum is more reactive than iron, this will corrode in preference to the iron. This technique has been used to protect street railway rails, plumbing, and marine vessel hardware. I might cast these pieces at home, before the conference.
