Uko Post mainly makes oil paintings in a realistic style, melancholic in atmosphere, related to Magical Realism and Neo-Romanticism. His themes are vanitas, emptiness, transience, themes that all people have to deal with and with which, according to the painter, they find it difficult to reconcile. He also finds a lot of inspiration in ancient European cultures, such as Greek and Roman culture and especially their decline. The Greek mythological stories also play a role in this. Furthermore, many paintings by Post are interwoven with the concept of the sublime, as described in Edmund Burke's famous book: A philosophical investigation into the origins of our ideas about the sublime and the beautiful from 1757. Ancient Egyptian culture also has his interests and is a valued source of inspiration.
