I don't believe that the remen was the oldest measure. I mean the first measure to relate to one minute of latitude.
The easiest measure to define this is the geographic foot which coincides with the Parthenon foot(see also Herodotus foot).
The dimensions of the Parthenon were based on the dimensions of Khafre's pyramid, and it's length to width to height ratio is the square of the width to height ration of Khafre's pyramid.
In my book Ieros Logos (in Greek) I look into metrology using different tools, like the fine structure constant. I read about the Parthenon geographic foot from Athanasios Aggelopoulos' books.
There are relationships between stadium lengths and the dimensions of the Sun, as also planets and satellites of our solar system.
There is thus a close proximity between between the geographic foot, the foot which I call photon foot, the parsec foot, the electron Moon foot, and the Mercury/Mars gravity foot.
The base of Khufu's pyramid can thus be accurately defined as 746 photon feet, with:
OGYGOS = 70+3+400+3+70+200 = 746
But my methodology also helped me define using a self consistent manner the royal cubit. This way the remen can also be derived using the square diagonal notion.
