Anamorphosis before 1583. "The Ambassadors" (c. 1533) by Hans Holbein the Younger is well known for the prominent oblique anamorphic transformation in the painting. In this artwork, a distorted shape lies diagonally across the bottom of the frame. Viewing this from an acute angle transforms it into the plastic image of a human skull. The painting is regarded as a "vanitas" - a meditation on the transience of life - with the skull a symbolic "memento mori". The altered perspective required to see the image reflects the contemporary practice of painting skulls on the reverse of otherwise tranquil paintings. Four centuries
Holbein stitch Holbein stitch Holbein stitch is a simple, reversible line embroidery stitch most commonly used in Blackwork embroidery and Assisi embroidery. The stitch is named after Hans Holbein the Younger (1497-1543), a 16th-century portrait painter best known for his paintings of Henry VIII and his children, almost all of whom are depicted wearing clothing decorated with blackwork embroidery. Although superficially similar to Back Stitch the Holbein stitch produces a smoother line and a pattern that is identical on both sides of the fabric. It can be worked in straight lines, diagonally, or in a stepped fashion to make a zigzag line
