1that it was made for the purpose of facilitating the watch over his house garden. Rami b. Hama enquired: Is it permitted to move an object two cubits along a roof and two cubits along a column? — ‘What an enquiry’, Rabbah exclaimed: ‘is this? He is asking about a karmelith and a private domain!’ And Rami b. Hama? — In his ingenuity he was not careful in putting the question. He, however, meant to put the question thus: Is it permitted to move an object two cubits along a roof and two cubits along an exedra? Do we say: Since neither the one nor the other is fit for a dwelling-place, both are regarded as a single domain; or is it possible that as he movement of objects from one roof to another is forbidden so is also that between a roof and an exedra forbidden. R. Bebai b. Abaye enquired: Is it permissible to move an object two cubits on a roof and two cubits in a ruin? — Is not this enquiry, R. Kahana asked, identical with that of Rami b. Hama? — Would I’, R. Bebai b. Aba e retorted: ‘have come with the enquiry of another man merely to cre te difficulties? An exedra is unfit as a dwelling whereas a ruin is fit’. But if it is fit as a dwelling why Uid he raise the question? — His enquiry was in the nature of an alternative question: If, [he said in effect,] you will find [some reason] for answering that an exedra is unfit as a dwelling, [will you agree that] a ruin is fit for a dwelling, or is it possible [that the latter is subject to thL same law as the former, since] nëw at any rate it has no tenants? — This must remain undecided. Regarding a number of roofs on the same level, according to R. Meir, or a single )oof, according to the Rabbis, Rab ruled: It is permissible to move objects through their ¯r[as, and Samuel ruled: Objects maÜ be moved only within four cubits. As ‘Rab ruled: It is permissi·le to move objeots throughout their areas, does not a contradiction arise between two rulings of Rab? There the walls are undistinguishable but, here, the wallsP are distinguishable. But since ‘Samuel ruled: Objects may be moved only within four cubitb’, does not a contradiction arise between two rulings of Samuel? — There the area was not bigger than two beth se'ah but here it is bigger than two beth se'ah, and, since those walls were made for dwelling purposes only below but not on the roof’ area above, the latter is like a karpaf bigger than two beth se'ah, that was not surrounded by walls for dwelling purposes, and in any karpaf bigger than two beth se'ah that was not surrounded by walls for dwelling purposes, no objects may be moved exc.pt within four cubits. It was stated: As regards a ship, Rab ruled: It is permissible to move objects about throughout its area, and Samuel ruled: Objects may be moved only wthin four cubits. ‘Rab“ruled: It is permissible to move objects about throughout its area’ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘᵛʷˣʸᶻᵃᵃᵃᵇᵃᶜᵃᵈᵃᵉᵃᶠᵃᵍᵃʰᵃⁱᵃʲᵃᵏᵃˡᵃᵐᵃⁿᵃᵒᵃᵖᵃᵠᵃʳᵃˢᵃᵗᵃᵘᵃᵛᵃʷᵃˣᵃʸ
2because it has walls; ‘and Samuel ruled: Objects may be moved only within four cubits’, since the walls were put up for the purpose of keeping out the water. ‘Is the law’, R. Hiyya b. Joseph asked Samuel, ‘in agreement with your view or is it in agreement with that of Rab?’ — ‘The law, the other replied: ‘is in agreement with that of Rab’. ‘Rab’, explained R. Giddal in the name of R. Hiyya b. Joseph, ‘agrees nevertheless that if it was turned upside down objects on it may be moved only within four cubits. For what purpose, however, was it inverted? If it be suggested: For the purpose of dwelling under it, why, it could be objected, should its law be different from that of a single roof? — It was inverted rather for the purpose of being coated with pitch. R. Ashi reported this with reference to a ship; but R. Aha son of Raba reported it with reference to an exedra. For it was stated: If an exedra was situated in a valley, it is, Rab ruled, permitted to move objects within all its interior; but Samuel ruled: Objects may be moved within four cubits only. Rab ruled that it was permitted to move objects in all its interior because we apply the principle: The edge of the ceiling descends and closes up. But Samuel ruled that objects may be moved within four cubits only because we do not apply the principle: The edge of the ceiling descends and closes up. But according to Rab's interpretation of R. Meir's view, should it not be permitted to move objects from a roof into a courtyard? This is forbidden as a measure of which R. Isaac b. Abdimi has spoken. And according to Samuel's interpretation of the view of the Rabbis, should it not be permissible to move objects from a roof to a karpaf? — Raba b. Ulla replied: The prohibition is due to a preventive measure against the possibility of a reduction in the area of the roof. But if so, it should also be forbidden to move an object from karpaf to karpaf since the area of one of them might happen to be reduced and people would still be moving objects from one to the other? — If a reduction were to occur there it would be noticeable but if a reduction should take place here it might not be noticed at all. Rab Judah stated: A careful study would show that according to the view of R. Meir roofs are regarded as a Separate domain, courtyards as a separate domainᵃᶻᵇᵃᵇᵇᵇᶜᵇᵈᵇᵉᵇᶠᵇᵍᵇʰᵇⁱᵇʲᵇᵏᵇˡᵇᵐᵇⁿᵇᵒᵇᵖᵇᵠᵇʳᵇˢᵇᵗᵇᵘᵇᵛᵇʷᵇˣᵇʸᵇᶻᶜᵃᶜᵇᶜᶜ
