Note 2245 — BOOK IV. AN ACCOUNT OF COUNTRIES, NATIONS, SEAS, TOWNS, HAVENS, MOUNTAINS, RIVERS, DISTANCES, AND PEOPLES WHO NOW EXIST OR FORMERLY EXISTED.
John Bostock translation
It is supposed that Pliny here alludes to Argos Hippium, which he has previously mentioned; but only in connection with the rivers Inachus and Erasinus, and not as included in the list of the towns of Argolis. The origin of the term “Dipsian” is probably unknown. It could hardly allude to drought, as Argos was abundantly supplied with water. But see B. vii. c. 57.
