The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the formula FeS2. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.

“Fernando Botero Angulo (born April 19, 1932) is a Colombian figurative artist. His works feature a figurative style, called by some “Boterismo”, which gives them an unmistakable identity. Botero depicts women, men, daily life, historical events and characters, milestones of art, still-life, animals and the natural world in general, with exaggerated and disproportionate volumetry, accompanied by fine details of scathing criticism, irony, humor, and ingenuity”. – Wikipedia

Zarnala is a female illustrator with a knack for anthropomorphic illustration, combining human and animal elements to create something altogether new. Unlike other forms of anthropomorphic art one can find out there though, her work always retains a tasteful, professional edge similar to the feel I get from comics like Juanjo Garnido's take on Blacksad. With an awesome watercolor themed approach to all her illustration work and her use of graphic shapes to frame her characters, at times it gives her art a strangely retro look that reminds one of the works of Norman Rockwell and JC Leyendecker. Check out more of her work after the break!

Italian pencil artist Marco Mazzoni‘s work goes far beyond technical perfection. His representation of historical healing women is enigmatic and sublime. Often leaving the eyes blank or covered with an abundance of birds, butterflies and flowers, he gives the impression of a deeper inward focused sight, as well as obscuring the identity of the individual. Many female healers in the past – both medicine woman and midwives – were brutally persecuted by religion, some even burnt as witches… Mazzoni’s work captures their deep connection with nature and their innate power and femininity with delicacy and beautiful detail.
