Drawing on laid paper, in 'sanguine' depicting a street with figures and a cart with wine barrels, in perfect condition. This technique was widely used in ancient times, especially for drawing, and consists of iron oxides mixed with clay and reduced into sticks. Usually, the sticks were mounted on special mechanical pencils and used for drawing. From this compound, also called 'hematite' because it recalls the color of blood, derives the modern noun 'pencil'. Particularly appreciated for the 'greasy' quality of its mark, and for the atmospheric effects it was able to produce, sanguine is one of the most used graphic tools by Renaissance artists.
