Leuca and Leucarum

AttestedLeuca at position 246 in the Ravenna Cosmogrpahy, in the sequence of harbour estuaries;  Leucaro on iter 12 of the Antonine Itinerary

WhereLeuca is the modern river Loughor, by Swansea.  Leucarum was a Roman fort, now underneath a Norman castle, at the mouth of the river, at SS563980.

Name origin:  PIE *leuk- ‘light, brightness’ presumably referred to the view over expanses of sand and mud in the estuary, as discussed in detail here.  The -arum part probably results from PIE *ar- ‘to fit together’ because the river Lliw joins the Loughor near the fort.
