The Peterborough Psalter
The penwork initials
Artists' Materials
Two types of large penwork initials mark the major text divisions. The simplest ones, executed in ultramarine blue and vermilion red ink, are flourished and filled with scrolling patterns in the contrasting colour. The more ornate ones, also executed in ultramarine blue and vermilion red ink, are filled with foliate ornament in multicoloured washes with occasional touches of gold. Pigments identified in these initials include verdigris, an organic yellow and a tan-coloured mixture, which probably contains lead white, an organic dye and possibly small amounts of other pigments.
