It seems that one of the most obvious aspect of Portrait is the protagonist’s issue with language. I think it reflects, especially towards the end of the text, the direction that he wants to develop his art. He champions for an Irish autonomy that unites instead of disunites — division that is based on an English vs Irish and/or Catholics vs Protestants rivalry. In other words, Language becomes an important premise in the driving forward of such a desire.
If we look at the scene between Stephen Dedalus and his dean, Stephen recognizes that the language he has been taught all his life is an “acquired speech” (195) and this serves as a reminder of his subservient position as he is being cast in the “shadow” (195) of a heritage that he does not identify with.
True enough, the English language belongs to the English or the Anglo-Saxons and differs from Irish historical heritage – that is, Gaelic. However, at the same time, the Irish language is becoming overly charged and associated negatively with (extreme) Irish nationalism. This deters Stephen from accepting it willingly becomes it disunites Irish people, it is obvious that Stephen adopts Parnell’s vision of unity where the differences of factions are negotiated and reached. I believe this is the reason for Stephen and even Joyce’s inclination towards something different, an art that uses the colonizer’s language (I guess strictly speaking, Ireland can be considered the colony of England) but undermines it by subsuming it within a Pan-European experience. And I guess this explains the framing of this text with Greek imageryand Latin, and not just English.
For one thing, Joyce’s inclination is illustrated by the name of Stephen Dedalus, where both names are of Greek origins. Furthermore, Dedalus is the name of a skillful artist from a Greek myth who designed the labyrinth to keep Minotaur ‘imprisoned’. Perhaps, Stephen, the artist and character is tasked with this task to use his art to keep ‘extremism’ and violence, as symbolised by Minotaur in check.
