I did this for a book cover design competition run by Venus Febriculosa. My design is inspired by gothic architecture and scholasticist philosophy, which lies at the heart of Eco's novel. I think I could've done something nice with the concept with a bit of time to fiddle and try things out, but it was a major rush-job again really.
But I guess it was useful to use Illustrator a bit for once, and I hadn't done anything design-related for ages. And one of the things I really love about this whole 'Illustration' idea is getting to learn about new things: I learnt a lot about medieval architecture, churches, 1300's philosophy and Italian Gothic while researching this.
