Note 69 — STATIUS'S THEBAIS.
Reading edition
The river Alpheus, which takes its rise in Arcadia, loses itself underground in parts of its course, and again reappears. This suggested the fiction that it ran in a subterranean channel, below the bottom of the sea, to the fountain of Arethusa in Sicily, where it once more emerged to day. Pope had less regard to the text of Statius than to Dryden's translation of Virgil's lines on the same legend in Ecl. x. 5:
So may thy silver streams beneath the tide, Unmixed with briny seas, securely glide.
