Question: What was depicted on the banners during the First Crusade of the same religious group who shattered a grand Mithraeum in Strasbourg

full_context: Document 1: Mosaic: The mosaics of the Church of St Stephen in ancient Kastron Mefaa (now Umm ar-Rasas) were made in 785 (discovered after 1986). The perfectly preserved mosaic floor is the largest one in Jordan. On the central panel hunting and fishing scenes are depicted while another panel illustrates the most important cities of the region. The frame of the mosaic is especially decorative. Six mosaic masters signed the work: Staurachios from Esbus, Euremios, Elias, Constantinus, Germanus and Abdela. It overlays another, damaged, mosaic floor of the earlier (587) "Church of Bishop Sergius." Another four churches were excavated nearby with traces of mosaic decoration.
Document 2: Castra of Cristești: Although not unanimously accepted, the existence of the castra of Cristești in the Roman province of Dacia is substantiated by bricks and tiles bearing the name of a Roman military unit, the "Ala I Gallorum et Bosporanorum". The lack of any other traces of the Roman fort may easily be due to its destruction by the Mureș River. At Cristeşti, a Roman settlement from the 2nd and 3rd centuries AD was unearthed which was an important center of potters.
Document 3: Red: Surveys show that red is the color most associated with courage. In western countries red is a symbol of martyrs and sacrifice, particularly because of its association with blood. Beginning in the Middle Ages, the Pope and Cardinals of the Roman Catholic Church wore red to symbolize the blood of Christ and the Christian martyrs. The banner of the Christian soldiers in the First Crusade was a red cross on a white field, the St. George's Cross. According to Christian tradition, Saint George was a Roman soldier who was a member of the guards of the Emperor Diocletian, who refused to renounce his Christian faith and was martyred. The Saint George's Cross became the Flag of England in the 16th century, and now is part of the Union Flag of the United Kingdom, as well as the Flag of the Republic of Georgia.
Document 4: Mosaic: Jerusalem with its many holy places probably had the highest concentration of mosaic-covered churches but very few of them survived the subsequent waves of destructions. The present remains do not do justice to the original richness of the city. The most important is the so-called "Armenian Mosaic" which was discovered in 1894 on the Street of the Prophets near Damascus Gate. It depicts a vine with many branches and grape clusters, which springs from a vase. Populating the vine's branches are peacocks, ducks, storks, pigeons, an eagle, a partridge, and a parrot in a cage. The inscription reads: "For the memory and salvation of all those Armenians whose name the Lord knows." Beneath a corner of the mosaic is a small, natural cave which contained human bones dating to the 5th or 6th centuries. The symbolism of the mosaic and the presence of the burial cave indicates that the room was used as a mortuary chapel.
Document 5: Red: In China, red (simplified Chinese: 红; traditional Chinese: 紅; pinyin: hóng) is the symbol of fire and the south (both south in general and Southern China specifically). It carries a largely positive connotation, being associated with courage, loyalty, honor, success, fortune, fertility, happiness, passion, and summer. In Chinese cultural traditions, red is associated with weddings (where brides traditionally wear red dresses) and red paper is frequently used to wrap gifts of money or other objects. Special red packets (simplified Chinese: 红包; traditional Chinese: 紅包; pinyin: hóng bāo in Mandarin or lai see in Cantonese) are specifically used during Chinese New Year celebrations for giving monetary gifts. On the more negative side, obituaries are traditionally written in red ink, and to write someone's name in red signals either cutting them out of one's life, or that they have died. Red is also associated with either the feminine or the masculine (yin and yang respectively), depending on the source. The Little Red Book, a collection of quotations from Chairman Mao Tse-Tung, founding father of the People's Republic of China (PRC), was published in 1966 and widely distributed thereafter.
Document 6: Red: Red played an important role in Chinese philosophy. It was believed that the world was composed of five elements: metal, wood, water, fire and earth, and that each had a color. Red was associated with fire. Each Emperor chose the color that his fortune-tellers believed would bring the most prosperity and good fortune to his reign. During the Zhou, Han, Jin, Song and Ming Dynasties, red considered a noble color, and it was featured in all court ceremonies, from coronations to sacrificial offerings, and weddings.
Document 7: Red: In Ancient Rome, Tyrian purple was the color of the Emperor, but red had an important religious symbolism. Romans wore togas with red stripes on holidays, and the bride at a wedding wore a red shawl, called a flammeum. Red was used to color statues and the skin of gladiators. Red was also the color associated with army; Roman soldiers wore red tunics, and officers wore a cloak called a paludamentum which, depending upon the quality of the dye, could be crimson, scarlet or purple. In Roman mythology red is associated with the god of war, Mars. The vexilloid of the Roman Empire had a red background with the letters SPQR in gold. A Roman general receiving a triumph had his entire body painted red in honor of his achievement.
Document 8: Hanover: Another point of interest is the Old Town. In the centre are the large Marktkirche (Church St. Georgii et Jacobi, preaching venue of the bishop of the Lutheran Landeskirche Hannovers) and the Old Town Hall. Nearby are the Leibniz House, the Nolte House, and the Beguine Tower. A very nice quarter of the Old Town is the Kreuz-Church-Quarter around the Kreuz Church with many nice little lanes. Nearby is the old royal sports hall, now called the Ballhof theatre. On the edge of the Old Town are the Market Hall, the Leine Palace, and the ruin of the Aegidien Church which is now a monument to the victims of war and violence. Through the Marstall Gate you arrive at the bank of the river Leine, where the world-famous Nanas of Niki de Saint-Phalle are located. They are part of the Mile of Sculptures, which starts from Trammplatz, leads along the river bank, crosses Königsworther Square, and ends at the entrance of the Georgengarten. Near the Old Town is the district of Calenberger Neustadt where the Catholic Basilica Minor of St. Clemens, the Reformed Church and the Lutheran Neustädter Hof- und Stadtkirche St. Johannis are located.
Document 9: Red: During the French Revolution, Red became a symbol of liberty and personal freedom used by the Jacobins and other more radical parties. Many of them wore a red Phrygian cap, or liberty cap, modeled after the caps worn by freed slaves in Ancient Rome. During the height of the Reign of Terror, Women wearing red caps gathered around the guillotine to celebrate each execution. They were called the "Furies of the guillotine". The guillotines used during the Reign of Terror in 1792 and 1793 were painted red, or made of red wood. During the Reign of Terror a statue of a woman titled liberty, painted red, was placed in the square in front of the guillotine. After the end of the Reign of Terror, France went back to the blue, white and red tricolor, whose red was taken from the traditional color of Saint Denis, the Christian martyr and patron saint of Paris.
Document 10: Red: Red, blue, and white are also the Pan-Slavic colors adopted by the Slavic solidarity movement of the late nineteenth century. Initially these were the colors of the Russian flag; as the Slavic movement grew, they were adopted by other Slavic peoples including Slovaks, Slovenes, and Serbs. The flags of the Czech Republic and Poland use red for historic heraldic reasons (see Coat of arms of Poland and Coat of arms of the Czech Republic) & not due to Pan-Slavic connotations. In 2004 Georgia adopted a new white flag, which consists of four small and one big red cross in the middle touching all four sides.
Document 11: Red: Red was the color of the banner of the Byzantine emperors. In Western Europe, Emperor Charlemagne painted his palace red as a very visible symbol of his authority, and wore red shoes at his coronation. Kings, princes and, beginning in 1295, Roman Catholic cardinals began to wear red costumes. When Abbe Suger rebuilt Saint Denis Basilica outside Paris in the early 12th century, he added stained glass windows colored blue cobalt glass and red glass tinted with copper. Together they flooded the basilica with a mystical light. Soon stained glass windows were being added to cathedrals all across France, England and Germany. In Medieval painting red was used to attract attention to the most important figures; both Christ and the Virgin Mary were commonly painted wearing red mantles.
Document 12: Bern: No archaeological evidence that indicates a settlement on the site of today′s city centre prior to the 12th century has been found so far. In antiquity, a Celtic oppidum stood on the Engehalbinsel (peninsula) north of Bern, fortified since the 2nd century BC (late La Tène period), thought to be one of the twelve oppida of the Helvetii mentioned by Caesar. During the Roman era, there was a Gallo-Roman vicus on the same site. The Bern zinc tablet has the name Brenodor ("dwelling of Breno"). In the Early Middle Ages, there was a settlement in Bümpliz, now a city district of Bern, some 4 km (2 mi) from the medieval city.
Document 13: Strasbourg: The centre of Argentoratum proper was situated on the Grande Île (Cardo: current Rue du Dôme, Decumanus: current Rue des Hallebardes). The outline of the Roman "castrum" is visible in the street pattern in the Grande Ile. Many Roman artifacts have also been found along the current Route des Romains, the road that led to Argentoratum, in the suburb of Kœnigshoffen. This was where the largest burial places were situated, as well as the densest concentration of civilian dwelling places and commerces next to the camp. Among the most outstanding finds in Kœnigshoffen were (found in 1911–12) the fragments of a grand Mithraeum that had been shattered by early Christians in the fourth century. From the fourth century, Strasbourg was the seat of the Bishopric of Strasbourg (made an Archbishopric in 1988). Archaeological excavations below the current Église Saint-Étienne in 1948 and 1956 unearthed the apse of a church dating back to the late fourth or early fifth century, considered to be the oldest church in Alsace. It is supposed that this was the first seat of the Roman Catholic Diocese of Strasbourg.
Document 14: Paris: The centre of Paris contains the most visited monuments in the city, including the Notre Dame Cathedral and the Louvre as well as the Sainte-Chapelle; Les Invalides, where the tomb of Napoleon is located, and the Eiffel Tower are located on the Left Bank south-west of the centre. The banks of the Seine from the Pont de Sully to the Pont d'Iéna have been listed as a UNESCO World Heritage Site since 1991. Other landmarks are laid out east to west along the historic axis of Paris, which runs from the Louvre through the Tuileries Garden, the Luxor Column in the Place de la Concorde, the Arc de Triomphe, to the Grande Arche of La Défense.
Document 15: Red: Red is the color most commonly associated with joy and well being. It is the color of celebration and ceremony. A red carpet is often used to welcome distinguished guests. Red is also the traditional color of seats in opera houses and theaters. Scarlet academic gowns are worn by new Doctors of Philosophy at degree ceremonies at Oxford University and other schools. In China, it is considered the color of good fortune and prosperity, and it is the color traditionally worn by brides. In Christian countries, it is the color traditionally worn at Christmas by Santa Claus, because in the 4th century the historic Saint Nicholas was the Greek Christian Bishop of Myra, in modern-day Turkey, and bishops then dressed in red.
