Abbán  Abbán moccu Corbmaic (; d. 520? AD), also Eibbán or Moabba, is a saint in Irish tradition. He was associated, first and foremost, with Mag Arnaide (Moyarney or Adamstown, near New Ross, Co. Wexford) and with Cell Abbáin (Killabban, County Laois). His cult was, however, also connected to other churches elsewhere in Ireland, notably that of his alleged sister Gobnait. Three recensions of the saint's "Life" survive, two in Latin and one in Irish. The Latin versions are found in the "Codex Dublinensis" and the "Codex Salmanticensis", while the Irish version is preserved incomplete in two manuscripts: the Mícheál Ó Cléirigh's manuscript Brussels, Royal Library MS 2324-40, fos. 145b-150b and also the RIA, Stowe MS A 4, pp. 205–21. These "Lives" probably go back to a Latin exemplar written in "ca". 1218 by the bishop of Ferns, Ailbe Ua Maíl Mhuaidh (Ailbe O'Mulloy), who died in 1223. His interest in the saint partly stemmed from the fact that Mag Arnaide lay within the diocese of Ferns, but as this was only a minor church in his time, more must have been involved. An episode which shows something of Ailbe's personal attachment to the saint's cult is that where the saint arrives in the area between Éile and Fir Chell, i.e. on the marches between Munster and Leinster: Abbán converts a man of royal rank from the area and baptises his son. Ailbe is known to have been a native of this area, but his own commentary as apparently preserved in the Dublin "Life" identifies the connection more nearly: "I who gathered together and wrote the Life am a descendant ["nepos"] of that son" However, the immediate circumstances which prompted the composition of the "Life" are likely to have been political, relating to Norman presence in the diocese of Ferns. To support his case, Ailbe made much of the saint's wider connections to other churches and saints, making him travel all across the country and in the case of the anecdote about Abingdon (see below), even inventing tradition.
