[PAULUS libro sexto decimo ad Sabinum. ] §41.1.29.prInter eos, qui secundum unam ripam praedia habent, insula in flumine nata non pro indiuiso communis fit, sed regionibus quoque diuisis: quantum enim ante cuiusque eorum ripam est, tantum, ueluti linea in directum per insulam transducta, quisque eorum in ea habebit certis regionibus.
[PAULUS, On Sabinus, book 16] Among those who own estates along the same bank, an island born in a river does not become common property in undivided shares, but rather with its regions also divided; for each of them will have in it, by specific regions, as much as lies in front of his own bank, just as if a line were drawn straight through the island.
