Pomponiana
Pomponiana Pliny (3.5) says that Pomponiana is the same as Mese, the middle island of the Stoechades or Isles d'Hières [STOECHADES], which lie close to the French coast east of Toulon. D'Anville, following the Maritime Itinerary, which places Pomponiana between Telo (Toulon) and Heracleia Caccabaria [HERACLEIA], thinks that Pomponiana is the peninsula of Giens, which is opposite to the western point of Prote (Porqueroles), the most western of the Stoechades. He remarks that the part of Giens which is on the land side is almost covered by a lagune, from which there are channels to the sea on both sides, so that the peninsula may be considered as an island.
