There is a longstanding argument as to whether the arms of the menorah in the Temple were straight or round. Sometimes, when two-sided arguments are found in the talmud the conclusion is, "both are correct."
And most of us hearing that conclusion ask, "They are saying opposite things so how can they both be right?"
And often the answer is, "When the Mashiach comes he will explain it."
But here with the Temple Menorah's seven arms inscribed the answer seems to have been found. This stone slab was found in Tiberias and was originally used as a door to a Jewish cemetery. The seven-armed menorah pictured here (the outer most semicircle ring is not an arm of the menorah) dates back from between the 2nd and 4th centuries CE. And it appears that the arms of the Menorah were both straight and round!
