[Ascension, or demonic figure?]

This loosely-rendered image is something of a mystery. We don't know who made it, nor do we know what the woman symbolizes. Some have suggested an accension, but it could equally be demonic. Why is her hair disheveled? Is her open mouth screaming or singing? Is that a garland suspended between her hands and draped across her lap? Are the wings her own or those of some angel or demon behind her? Does she enter through a spreading curtain or sit up high betwen gothis arches? Sometimes art leaves us completely to our own imaginations.
