A river of[1] the Arcadian city [of that name], which is situated in the Peloponnese. Reaching open water through the Adriatic Sea, and mixing in no way with the brine, it surges up by the island of Sicily around the spring called Arethusa, as if it were her beloved.[2]
"But here's someone running and breathing Alpheus".[3] Thus swiftly, as if an Olympic runner, derived from the river flowing by.[4]
I think the Theologian is speaking about this [sc. when he says] "and if some river is believed to flow sweet through sea-water".[5]
