Retna is an American street and graffiti artist from Los Angeles, recognized around the world for his unique calligraphy art based on his own, self-constructed, ancient-looking geometric script, inspired by traditional symbols on Native Americans and Egyptian hieroglyphs. He invented a distinctive constructed script and incorporated it, in one way or another, in all of his paintings and murals. Because of the uniqueness and visual appeal of these constructed letters, Retna became one of the most prosperous street artists, nowadays working with high-end clients and campaigns.
