Mark Lombardi has been a great conceptual artist.
He renewed the "history painting" bringing it closer to our age, depicting entangled relationships between people, corporations and institutions.
And, of course, the most appealing thing to me is that he used concept maps for his diagrams, well, sort of.
His drawings have a formal taste, as well as an artistic flavour, his aesthetics reveal emergent patterns, highlight key roles and, the most
important thing, drive the reader/watcher through the experience.

I’ve been a Lombardi enthusiast since the beginning of my thesis and i’m now studying the only book available about him: "Global Networks", which portrays a lot of his works.
Maps are so powerful, but maps are not graphs, they just cannot be arranged
by an algorithm.. a man, or a group, must gather, share knowledge and draw it in a meaningful way.
Lombardi was alone, and i wonder if in the world there exist an active constructivist map-building community..
By the way, if you own a video about Lombardi (2003, Andy Mann), let me know!
