Artes mechanicae

Artes mechanicae (mechanical arts) are a medieval concept of ordered practices or skills, often juxtaposed to the traditional seven liberal arts (artes liberales). Also called "servile" and "vulgar", from antiquity they had been deemed "unbecoming" for a free man, as they minister to basic needs.

Overview
Johannes Scotus Eriugena (9th century) divided them into seven parts: Leonardo Da Vinci developed the mechanical form of painting in which a synthesis of Roman and Greek forms of art was attempted. The paint was manipulated in a number of different ways each driven by ideas surrounding process, materiality and chance encounters. The unique display of forms and colours were brought together by the artist's hand but manipulated though the use of machines or natures forces.
 * vestiaria (tailoring, weaving)
 * agricultura (agriculture)
 * architectura (architecture, masonry)
 * militia and venatoria (warfare and hunting, military education, "martial arts")
 * mercatura (trade)
 * coquinaria (cooking)
 * metallaria (blacksmithing, metallurgy)

In his Didascalicon, Hugh of St Victor (12th century) includes navigation, medicine and theatrical arts instead of commerce, agriculture and cooking. Hugh's treatment somewhat elevates the mechanical arts as ordained to the improvement of humanity, a promotion which was to represent a growing trend among late medievals.

The classification of the artes mechanicae as applied geometry was introduced to Western Europe by Dominicus Gundissalinus (12th century) under the influence of his readings in Arabic scholarship.

In the 19th century, "mechanic arts" referred to some of the fields that are now known as engineering. Use of the term was apparently an attempt to distinguish these fields from creative and artistic endeavors like the performing arts and the fine arts, which were for the upper class of the time, and the intelligentsia. The mechanic arts were also considered practical fields for those that did not come from good families.

Related phrases, "useful arts" or "applied arts" probably encompass the mechanic arts as well as craftsmanship in general.

The most famous usage of the term "mechanic arts" (and the one in which it is most commonly encountered today) is in the Morrill Land-Grant Colleges Act.
