All black is too unimaginative to be Goth. Corsets are one of my oldest and most telltale dressing favorites. Art history - It's nice to know a Waterhouse from a Rossi. There's always the sociological insights on a given time period and place that only the study of their art can give you. Writing - I just can't limit my imagery to canvas.
Words are just as potent as pictures, and carry ideas more explicitly in some cases.
Mythology - regardless of what culture it comes from, it's always wonderful and brilliant. Not to mention it's another way to understand who they were and what they were thinking. I have also undertaken the production of a magazine devoted to reshaping people's perceptions of Goth and started up a web design contracting company. All gods are the same to me, so long as their followers keep their religions to themselves and don't mess with my life. I really couldn't say.
