  Title: Eblani
  Passage: The Eblani ( Ἐβλάνοι) or Eblanii ( Ἐβλάνιοι) (manuscript variants: Ebdani [ Ἐβδανοί]; Blani [Βλάνοι]; Blanii [Βλάνιοι]) were a people of ancient Ireland uniquely recorded in Ptolemy's 2nd-century "Geography", in which they inhabit a region on the east coast, roughly north of County Dublin.  Ptolemy also lists a "city" called Eblana ( Ἔβλανα), which he locates between the estuaries of the rivers Buvinda (Βουουίνδα) and Oboca (᾿Οβόκα), implying a coastal site between the Boyne and probably the Liffey respectively.  O'Rahilly tentatively suggested that the tribal name, which he speculatively reconstructed as "*Ebodanī", may have survived in the toponym Edmann, a region on the east coast, probably in County Louth, occasionally mentioned in early texts.  O'Rahilly's line of reasoning was inspired by the form "Ebdanoi" [ Ἐβδανοί] found in one manuscript family of Ptolemy's work, but this variant is demonstrably the result of a transcriptional error for "Eblanoi" ( Ἐβλάνοι) in a majuscule script, where Λ has been misread as Δ, and not vice versa as O'Rahilly reasoned.  This defective reading cannot therefore be cited in support of his hypothesis.
