Chalice - Stoneware - German historian circa 1880.

The object in the image is an example of the 'Historicism' style, which was popular in the 19th century.
Historicism refers to a 19th-century art movement in which artists and architects drew inspiration from historical styles such as Gothic, Renaissance, or Baroque. The cup imitates the style of salt-glazed pottery from the Westerwald, originally produced in the 16th and 17th centuries. The design features traditional blue and gray colors and reliefs, including medallions with a knight's helmet, reminiscent of historical motifs and coats of arms.
This type of pottery was often made as a nostalgic tribute to older German traditions and craftsmanship during the period of national consciousness in the 19th century.
