Saint Maurice - Wikipedia

en.wikipedia.org

Saint Maurice (also Moritz, Morris, or Mauritius; Coptic: Ⲁⲃⲃⲁ Ⲙⲱⲣⲓⲥ) was the leader of the legendary Roman Theban Legion in the 3rd century, and one of the favorite and most widely venerated saints of that group. He was the patron saint of several professions, locales, and kingdoms. He is also a revered saint in the Coptic Orthodox Church of Alexandria and other churches of Oriental Orthodoxy

According to the hagiographical material, Maurice was an Egyptian, born in AD 250 in Thebes, an ancient city in Upper Egypt that was the capital of the New Kingdom of Egypt (1575-1069 BC). He was brought up in the region of Thebes (Luxor)

However, when Maximian ordered them to harass some local Christians, they refused. Ordering the unit to be punished, Maximian had every tenth soldier killed, a military punishment known as decimation. More orders followed, the men refused compliance as encouraged by Maurice, and a second decimation was ordered. In response to the Theban Christians' refusal to attack fellow Christians, Maximian ordered all the remaining members of his legion to be executed. The place in Switzerland where this occurred, known as Agaunum, is now Saint-Maurice, Switzerland, site of the Abbey of St. Maurice.
So reads the earliest account of their martyrdom, contained in the public letter which Bishop Eucherius of Lyon (c. 434–450), addressed to his fellow bishop, Salvius. Alternative versions[citation needed] have the legion refusing Maximian's orders only after discovering innocent Christians had inhabited a town they had just destroyed, or that the emperor had them executed when they refused to sacrifice to the Roman gods.

Saint Maurice became a patron saint of the German Holy Roman Emperors. In 926, Henry the Fowler (919–936), even ceded the present Swiss canton of Aargau to the abbey, in return for Maurice's lance, sword and spurs. The sword and spurs of Saint Maurice were part of the regalia used at coronations of the Austro-Hungarian emperors until 1916, and among the most important insignia of the imperial throne. In addition, some of the emperors were anointed before the Altar of Saint Maurice at St. Peter's Basilica.[1] In 929, Henry the Fowler held a royal court gathering (Reichsversammlung) at Magdeburg. At the same time the Mauritius Kloster in honor of Maurice was founded. In 961, Otto I, Holy Roman Emperor, was building and enriching Magdeburg Cathedral, which he intended for his own tomb.

This statue of St. Maurice in Magdeburg Cathedral dates from around 1240 and was probably made by the anonymous sculptor of the well-known Magdeburg Rider. The sculpted features of Maurice’s face and the coloring unambiguously identify him as a black man, but this is no demeaning caricature. This naturalistic, lifelike figure is an admirable warrior armed with his characteristic spear, which he once held in his right hand. In this statue, the earliest depiction of St. Maurice as a black man, we see an innovation in medieval depictions of blackness that challenged negative stereotypes and insisted instead on a Christian egalitarianism that transcended any color difference.

It was in this context that St. Maurice became a black man where he had previously been depicted as light-skinned, first in two passages from a Regensburg chronicle (ca. 1160) that described him as the commander of a troop of “black moors” and then in this statue. It is not clear whether the statue was commissioned on Frederick’s orders, as Paul Kaplan suggests, or whether the Archbishop Albert II had commissioned the statue on his own initiative, as Gude Suckale-Redlefsen argues, but in any event the image of the black saint proved a powerful propaganda tool for the Hohenstaufen ruler. As had been true for his father Henry VI, Frederick II understood that depictions of the variety of subjects in his cosmopolitan empire were useful for buttressing his authority. By depicting this paragon of Christian strength as a black man, Frederick highlighted the reach of both his faith and his political power, a useful propaganda tool against unruly nobles and recalcitrant

He was a patron Saint of Infantry...

Patronage[edit]
Maurice is the patron saint of the Duchy of Savoy (France) and of the Valais (Switzerland) as well as of soldiers, swordsmiths, armies, and infantrymen. In 1591 Charles Emmanuel I, Duke of Savoy arranged the triumphant return of part of the relics of Saint Maurice from the monastery of Agaune in Valais.[14]

He is also the patron saint of weavers and dyers. Manresa (Spain), Piedmont (Italy), Montalbano Jonico (Italy), Schiavi di Abruzzo (Italy), Stadtsulza (Germany) and Coburg (Germany) have chosen St. Maurice as their patron saint as well. St Maurice is also the patron saint of the Brotherhood of Blackheads, a historical military order of unmarried merchants in present-day Estonia and Latvia.[15] In September 2008, certain relics of Maurice were transferred to a new reliquary and rededicated in Schiavi di Abruzzo (Italy).

He is also the patron saint of the town of Coburg in Bavaria, Germany. He is shown there as a man of colour especially on manhole covers as well as on the city coat of arms. There he is called "Coburger Mohr" (engl.: "Coburg


Here is Saint Barbara the patron saint of artillery...

https://en.wikipedia.org/wiki/Saint_Barbara

Patronage
Saint Barbara is venerated by Catholics who face the danger of sudden and violent death at work. She is invoked against thunder and lightning and all accidents arising from explosions of gunpowder.[13][14] She became the patron saint of artillerymen, armourers, military engineers, gunsmiths, and anyone else who worked with cannon and explosives.[15][16] Following the widespread adoption of gunpowder in mining in the 1600s, she was adopted as the patron of miners, tunnellers,[11] and other underground workers. As the geology and mine engineering developed in association with mining, she became patron of these professions.

The Spanish word santabárbara, the corresponding Italian word santabarbara, and the obsolete French Sainte-Barbe, signify the powder magazine of a ship or fortress.[17] It was customary to have a statue of Saint Barbara at the magazine to protect the ship or fortress from suddenly exploding.[17] Saint Barbara is the patron of the Italian Navy.[13][16]

Within the tunnelling industry, as a long-standing tradition, one of the first tasks for each new tunnelling projects is to establish a small shrine to Santa Barbara at the tunnel portal or at the underground junction into long tunnel headings. This is often followed with a dedication and an invocation to Santa Barbara for protection of all who work on the project during the construction period.[18][19]

Moors, Saints, Knights and Kings: The African Presence in Medieval and Renaissance Europe

The study of the African presence in history, whether in the African Diaspora or Africa itself, is a richly rewarding endeavor. In this study we realize that slavery alone is not African history and that African history is everybody’s history. The history of African people — Black people — is rich and comprehensive, inspiring and, often, little known. Nowhere is this more the case than the African presence in Medieval and Renaissance Europe.

According to the Oxford English Dictionary, the Moors, as early as the Middle Ages and as late as the 17th century, were “commonly supposed to be black or very swarthy, and hence the word is often used for Negro.”
