Eruvin

On April 29, 2010 · 1 Comments

Have you ever posted something with a little trepidation, feeling there’s a likelihood that you’re going to screw it up? I’m just going to start this off right away by providing an upfront apology to anyone of the Jewish faith. I’ll do my best to focus on geography and hopefully a knowledgeable readership will assist me with the finer points of religious reasoning and logic behind the phenomenon. Please be gentle with your comments as no offense is intended.

I’m absolutely fascinated by the concept of the eruv chatzerot, commonly shortened simply to eruv or to its plural form, eruvin.

The Torah prohibits a number of activities on Shabbat, the Jewish Sabbath, including the carrying of objects from one domain to another, say from a home into a public space or across some other property line. Not all Jews follow this prohibition but many do. For them, imagine the practical limitations when they are unable to carry anything through their doorway except for the clothing on their back. These provisions have been handed down through the ages and hold significant religious meaning for countless observant Jews. The prohibitions aren’t going to change. However rabbinical interpretations do provide a few flexibilities.

Belongings can be carried within the home but they cannot be transported to the outside world on Shabbat. What is home, though? This is where the Eruv begins to address the situation. Individual homes can be combined into a collective home by the consent of all property owners. A classic example would be a walled courtyard formed by the perimeter of several private residences. They could be joined to form an Eruv Chatzerot (an “aggregation of courtyards”) in a religious ceremony. Objects can be transferred freely within the Eruv while continuing to respecting the provisions of the Torah since the entire area becomes a "home."

An eruv must be formed by an enclosure of walls and door frames of certain dimensions. Perhaps there are some campus environments that exist within walled compounds in the modern age but walled cities are generally a relic of the past. Yet there are plenty of Eruvin that cover large metropolitan areas. So how do they do it? By forming lots and lots of door frames.

The doorways are created with wires and posts, often utility poles. A "door frame" might consist of wires running down adjacent utility pole with a wire strung between them. It’s a door frame a symbolic sense but it’s deemed as an acceptable solution for the purpose of an eruv. Large urban and suburban areas can be gathered within a single eruv using this method. It is a rather porous walled courtyard but it can be constructed in such a manner as to meet the religious definition.

Theoretical considerations don’t limit the size of an eruv but practical limitations make it difficult to maintain after a certain point. The eruv has to be checked thoroughly each week before sundown Friday to ensure the integrity of the enclosure. One small break found anywhere along the perimeter invalidates the entire eruv. It might take only a good thunderstorm or a clueless utility worker to create a fatal breach. It’s not an eruv on Shabbat if it’s not repaired by Friday at sundown. Various websites track the status of eruvin so that people can tell whether they are in effect and when they are down. Also of note, different rabbis may interpret the the technical characteristics differently so an eruv maybe valid to some but may not be recognized by others. It can get complicated.

Each of the maps on the page is an eruv. I have not created any of these maps, instead, I’ve linked to actual eruv maps constructed for the purpose of keeping people informed of the boundaries. You can always see more by going to Google Maps and searching on the term Eruv Maps using the Show Search Options / User-Created Maps feature. I could find only interactive maps of eruvin in the United States probably because I searched in English. Practically every Jewish community in Israel has one and they should be easy to find if you know Hebrew, which I do not.

Eruven exist in many other places around the world. I even found one in Northwest London. It’s a static map but the boundaries are clearly defined.

I’m sure I made some errors due or oversimplification and lack of expertise but I do hope I got the majority of intent correct. I’ve known of eruvin conceptually for a long time but I didn’t realize these "walled courtyards" existed in so many places that I’ve traveled through and I’ve never noticed them. I can’t wait to look for some of their door frames.
