About
About Meson — Lake Moeris Harbour at Fayum Southwest (Harbour of Moeris Southwest)
Southwest harbour of Lake Moeris at Meson, where the westernmost Fayum canal port now lies 1–2 m silted behind Wadi Rayyan bar southwest of Dionysias already in batch, Meson preserves limestone quay 50 m at –1.8 m with mooring stones, southwest canal sluice 6 m at –2 m and Ptolemaic granary 20×12 m at –1 m mapped 2014 Fayyum Southwest survey coring. Founded Ptolemy II c. 270 BCE as Moeris southwest grain port for Wadi Rayyan oasis, Meson shipped Fayum southwest wheat via Moeris loop until 300 CE canal failure. Harbour silt seals Ptolemaic tile horizon over Middle Kingdom dyke. Meson channel linked Moeris to Rayyan depression.
Why it mattersMeson harbour proves Moeris southwest loop beyond Dionysias; Rayyan bar stratigraphy anchors Moeris southwest desiccation and Fayum southwest grain chronology.
