Porphyreon

Historians of the Crusades (William of Tyre and James of Vitry) confound this town with Caipha; the latter corresponds to the see.

In fact Simeon Stylite the Young, contemporary of Paul, Bishop of Porphyreon, affirms[7] that the episcopal town may be found near Castra, a place inhabited by the Samaritans.

Now, in the same epoch the Pseudo-Antoninus [8] locates the Castra Samaritanorum a Sucamina (Caipha) milliario subtus monte Carmelo south of Porphyreon.

[9] The ruins of Porphyreon should be found near Belus, the Nahr Namein, in the sands of which may still be seen the murex brandaris and the murex trunculus (thorny shell fish), from which is extracted the famous purple dye of Tyre, and which gave its name to Porphyreon.

The Napoleonic era map survey of Pierre Jacotin marks the Ruines de Porphyrion as being located a kilometre north-east of the grotte d'Elie (now the site of the Stella Maris Monastery).
