The pleated garment is comparable with those seen on figurines of females, interpreted as Valkyrie, found in Denmark. It looks to me as if she may be modelled on the Roman goddess Fortuna. A medieval Fortuna can be seen in a manuscript of Carmina Burana.
It's interesting that Jupiter was said to have been Fortuna's father and that Odin was the Norse equivalent of Jupiter. Odin's daughters were valkyries. See: http://lifeartearth.blogspot.com/2014/12/a-speculative-connection-between.html
According to Price (2014), "Representations of female figures can be understood in a number of different ways, and may represent a range of supernatural forces including goddesses, valkyries, norns and disir."
Another very different interpretation of this figure is that it represents a robed saint carrying a cross and I am currently inclined to favour this view.
