Marco background is in engineering and architecture, he’s been using math and geometry all his life, when he decided to apply his skills to art, one of the first things he chose to do was cartography. He applies traditional technique to the maps he draws, like multiple Cartesians coordinates and polar system coordinate. The maps are done in ink, acrylic, watercolour and gild on canvas. In his Mappa Mundi he includes charts for positioning at sea using star systems , revolution of the sun charts and astronomical charts. The more decorative part of the map is done in ink.
