Raphana

Raphana (Ραφάνα in Ancient Greek), was one of the Decapolis cities mentioned by Pliny the Elder, within his Naturalis Historia (Book V.74).

Raphana was sought for the last two millennia, after no one could identify this ancient settlement, as it was mostly omitted from maps or in scientific literature.

This fits also to the history of Flavius Josephus, who describes the forts around a place called Raepta, which is very plausibly the predecessor settlement of Raphana.

In some online sites you can read that Raphana was at the "Abilene plain" and some mixed this name again with Abila at Wadi Queilbeh south of the Yarmuk, but the Abilene Plain describes a completely different region and the area around Abila Lysaniae, which is north-west of Damascus and always connected with the Paneas region too.

The notation at the Notitia Dignitatum at "Arefa" shows us for a later date that there was a military unit, an ala at that location.
