Hatching (French: hachure) is an artistic technique used to create tonal or shading effects by drawing, painting, or scribing closely spaced parallel lines. When lines are placed at an angle to one another, it is called cross-hatching. Hatching is also sometimes used to encode colours in monochromatic representations of colour images, particularly in heraldry.

Hatching is especially important in essentially linear media, such as drawing and many forms of printmaking, such as engraving, etching, and woodcut. In Western art, hatching originated in the Middle Ages and developed further into cross-hatching, especially in the old master prints of the fifteenth century. Master ES and Martin Schongauer in engraving and Erhard Reuwich and Michael Wolgemut in woodcut were pioneers of both techniques. Albrecht Dürer in particular perfected the technique of crosshatching in both media.

Master E. S. (c. 1420 – c. 1468; previously known as the Master of 1466) is an unidentified German engraver, goldsmith, and printmaker of the late Gothic period. He was the first major German artist of old master prints and was greatly copied and imitated. The name assigned to him by art historians, Master E. S., is derived from the monogram, E. S., which appears on eighteen of his prints (variants appear on others). The title, Master, is used for unidentified artists who operated independently. He was probably the first printmaker to place his initials on his work.

Remaining signed works by E. S. indicate that he was active in printmaking from 1450 to 1467, the latest date to appear on one of his prints. After this date, he is presumed to have died. He was the most distinguished German engraver before Martin Schongauer.

The Buhl Altarpiece (French: Retable de Buhl) is a late 15th-century, Gothic altarpiece of colossal dimensions now kept in the parish church Église Saint-Jean-Baptiste of Buhl in the Haut-Rhin département of France. It was painted by followers of Martin Schongauer, most probably for the convent of the Dominican sisters of Saint Catherine of Colmar, and moved to its present location in the early 19th century. It is classified as a Monument historique by the French Ministry of Culture (see below, History).

The altarpiece depicts five scenes from the Passion of Jesus, four scenes from the Life of the Virgin, and a Last Judgment.

Hortus conclusus is a Latin term, meaning literally "enclosed garden". Both words in hortus conclusus refer linguistically to enclosure. It describes a type of garden that was enclosed as a practical concern, a major theme in the history of gardening, as walled gardens used to be more commonplace. The garden room is a similar feature, usually less fully enclosed.

Having roots in the Song of Songs in the Hebrew scriptures, the term hortus conclusus has importantly been applied as an emblematic attribute and a title of the Virgin Mary in Medieval and Renaissance poetry and art, first appearing in paintings and manuscript illuminations about 1330.
