Saint: a pure or holy person.  In the early Middle Ages, saints were recognized after their death by popular acclaim for having performed miracles; by the high Middle Ages the recognition of miracles had come to be surrounded by a formal canonization process, like a legal trial.  Saints were thought to be able to intercede for a particular individual or group with Christ: Thus, most regions, churches and occupations had a particular "patron saint." Some saints were identified with particular situations: thus, for example, St Margaret was invoked during childbirth, St Christopher to ensure a safe journey, St Roch against the plague. Most saints had a particular "saints day" on which he or she was particularly venerated. Saints continue to be venerated up to the present day- for example the patron saint of computers is St. Isodore of Seville.

Attribute: Symbol which identifies a saint. For example, St Peter is represented carrying keys; St Apollonia holds pincers and a tooth, as patron of dentists and people with toothache; St Gertrude is surrounded by rats and mice, against whom she is invoked.

Relic: an object of veneration, usually the body of a saint, or a portion of the body, or an object associated with a saint, such as the veil of the Virgin, a piece of the Holy Cross, the Crown of Thorns, etc. During the medieval period, the cult of relics was of great importance, as churches collected relics and built special containers and shrines for them; and pilgrims traveled long distances to venerate them and to expect cures or other indications of recognition through the intercession of the saints.
