Four versions of the "Shield of the Trinity" or "Scutum Fidei" diagram of traditional Christian Trinitarian symbolism, illustrating some variant depictions:
1. A shield-shaped version on red shield, attributed as the heraldic arms of God (or of the Trinity) in medieval England and France.  See "The Heraldic Imagination" by Rodney Dennys.  For a stand-alone version, see Image:Shield-Trinity-medievalesque.svg .   For a photograph of a probable 19th-century church decoration, see File:Scutum_Fidei_on_Holy_Trinity_pulpit_-_geograph.org.uk_-_1061634.jpg .  (For a differently-colored rendering, see Image:St-Faith-Arms.png .)
2. Rounded form with single vertex up, popularized by the "Handbook of Christian symbolism" by George Ashdown Audsley and William James Audsley (published in 1865).  (See also File:Trinity triangle (Shield of Trinity diagram) 1896.jpg.)
3. Color-coded version, with the positive or asserting parts of the diagram in black, and the negative or denying parts of the diagram in red.  Similar to the version in the 15th century stained glass window in St. Peter and St. Paul church, Fressingfield, Suffolk, England (which only includes the positive parts of the diagram).  For other color-coded versions, see File:Shield of Trinity in hexagon.svg, File:Shield of Trinity in hexagon English.svg.
4. Translated version with English-language captions.
