Fantasy art has been largely considered "low brow" ever since, thanks to every common man or woman drawing their own fantastical creatures or stories.
Fantasy art is historically rooted in mythology, folklore and religious art from all over the globe. Fantasy art is a mixture of imagination and direct observation of reality. It takes reality and adds a fanciful, unrealistic, fantastic, dreamy, wistful feeling to it. Essentially the result of artists with wild imaginations.
Artists turned to painting the unseen their imaginations ran wild. Today, fantasy art continues to be extremely popular where artists and art lovers can enjoy sci fi, surreal, mythological, unexplainable, imaginative, and taboo themes.
