Eblana - Eblana As Dublin

Eblana As Dublin

If the reference to a settlement in Ireland called Eblana is in fact the earliest reference to Dublin, this would seem to give Dublin a just claim to nearly two thousand years of antiquity, as the settlement must have existed a considerable time before Ptolemy became aware of it.

Early Irish antiquarians, such as Sir John Ware and Walter Harris believed that the name Eblana in Ptolemy's Geographia was in fact a corruption of Deblana, itself a version of the Gaelic name Dubh Linn (Black Pool), from which the modern English language name Dublin derives. For one reason or another, it seems, ancient geographers often truncated the initial letters of place names. For example, instead of Pepiacum, and Pepidii (in Wales), Ptolemy writes Epiacum and Epidii; and for Dulcinium (now Ulcinj, in Montenegro), he has Ulcinium.

There are several problems with this theory:

• The earliest Gaelic settlement on the site of Dublin is referred to in local sources as Áth Cliath ("Ford of Hurdles"). Duiblinn first appears as the name of a Christian ecclesiastical settlement which could not possibly have existed before the 5th century.

• Ptolemy's description of Ireland shows no trace of either the Goidelic or Laginian occupations of the country, both of which probably took place some centuries before Ptolemy's time. O'Rahilly (1946) has concluded from this that his description is probably based on data collected in the 4th century BC by the early explorer Pytheas.

• Some early texts of Ptolemy's Geographia call the settlement in question Ebdana (the Greek uppercase letters lambda and delta are similar and easily confused: Λ and Δ). Considering the degree of corruption which Ptolemy's work is known to have suffered in transmission, it is impossible to tell which, if either, of these variants is the correct form.

• The co-ordinates Ptolemy gives for Eblana places the settlement in the north of County Dublin, several kilometres from the site of the modern city of Dublin.

• Ptolemy's Eblana did not stand on a river. In the Geographia, Eblana occurs between the mouths of two rivers: the Buvinda (i.e. the River Boyne) and the Oboka. Because early antiquaries believed that Eblana was Dublin, they identified the Oboka with the river which enters the sea at Arklow in County Wicklow, which they consequently dubbed the Ovoca (now the River Avoca). In fact, Ptolemy's Oboka seems to be the River Liffey, and his Modonnos probably represents the Avoca. Eblana, thus, is located somewhere between the mouths of the Boyne and the Liffey.
