Poppi created these studies in the 16th century, using red chalk on paper. Chalk is interesting because it’s so basic: just a readily available stone, ground into a powder and then formed into a usable stick. But look closely at the artist's skill in how he coaxes the material to describe the body of Christ, supported by an angel. Chalk allows for a full range of effects, from the crisp lines that define contours to the broader strokes used to indicate shadow and volume. You can almost feel the weight and texture of the body, even on a flat sheet of paper. In the Renaissance, drawing was seen as the foundation of all artistic practice. Chalk was a common choice for preparatory sketches and studies, valued for its immediacy, and relative affordability. These quick, almost ephemeral drawings were essential to a painter's process. Next time you see a finished painting from this period, remember that it likely began with humble materials like this, and represents a huge amount of labor, as well as the creative spark of the artist.
