Do we really own our homes? What about the earth below it? The sky above? How far below or above? What does that mean? Our daf explains:
We learned in the mishna: If one placed the eiruv in a pit, even if it is a hundred cubits deep, his eiruv is a valid eiruv. The Gemara asks: This pit, where is it situated? If you say that it is situated in the private domain, it is obvious, for the private domain ascends to the sky, and just as it ascends upward, so too, it descends downward to the bottom of the pit, even if it is more than ten handbreadths deep. Rather, we must say that the pit is situated in the public domain.
This legal concept is not solely the purview of the Talmud. It is also encoded in the Latin, cuius est solum, eius est usque ad coelum et ad inferos (“Whoever owns the soil, it is theirs up to Heaven and down to Hell.”), which appears in medieval Roman law and is credited to Accursius (13th-century).
This law was not really challenged until technology threw this belief into question: city pipes and subways underground, and airplanes and building rights in the sky above. I have a friend who is a professor of aviation law, and this is an area that she teaches: air rights for the landowners. While I find the legalities interesting, my gem is really a challenge to the idea that anyone can own land or sky. There are myriad rules about how we cannot do damage, even to what we “own” if it causes hard to others. Two of my favorite examples follow:
Midrash: Vayikra (Leviticus) Rabbah– 4:6
If one Jew sins, all of Israel feels it….This can be compared to the case of men on a ship, one of whom took a drill and began drilling beneath his own place. His fellow travelers to said to him: ‘what are you doing?’ He replied: ‘What does that matter to you, I am drilling only under my own place?’ They continued: ‘We care because the water will come up and flood the ship for us all.’
A Chasidic Tale (This is based upon his understanding of Bava Batra 37a and b which discusses conflicts in ownership of land during the shmitah year.): Two men were fighting over a piece of land. Each claimed ownership and bolstered his claim with proof. To resolve their differences, they agreed to put the case before the rabbi. The rabbi listened but could not come to a decision because both seemed to be right. Finally he said, “Since I cannot decide to whom this land belongs, let us ask the land.”. He put his ear to the ground, and after a moment straightened up. “Gentlemen, the land says that it belongs to neither of you – but that you belong to it.”
