Rome (/ˈroʊm/; Italian: Roma pronounced [ˈroːma] ( listen); Latin: Rōma) is a city and special comune ("Roma Capitale") in Italy. Rome is the capital of Italy and the capital of Lazio (Latin: Latium). With 2.8 million residents in 1,285.3 km² (496.3 sq mi), it is also the country's largest and most populated comune and fourth-most populous city in the European Union by population within city limits. Between 3.2 and 3.7 million people live in the Rome metropolitan area. The city is located in the central-western portion of the Italian Peninsula, on the Tiber River within the Lazio region of Italy.

Rome's history spans two and a half thousand years. It was the capital city of the Roman Kingdom, the Roman Republic and the Roman Empire, which was the dominant power in Western Europe and the lands bordering the Mediterranean for over seven hundred years from the 1st century BC until the 7th century AD and the city is regarded as one of the birthplaces of western civilization. Since the 1st century AD Rome has been the seat of the Papacy and, after the end of Byzantine domination, in the 8th century it became the capital of the Papal States, which lasted until 1870. In 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic.

Lawrence of Rome (Latin: Laurentius, lit. "laurelled"; c. 225 – 258) was one of the seven deacons of ancient Rome, serving under Pope St. Sixtus II, who were martyred during the persecution of Valerian in 258.

According to lore, among the treasures of the Greek church entrusted to Lawrence for safe-keeping was the Holy Chalice, the cup from which Jesus and the Apostles drank at the Last Supper. Lawrence was able to spirit this away to Huesca, in present day Aragon, with a letter and a supposed inventory, where it lay hidden and unregarded for centuries. When Augustine connects Lawrence with a chalice, it is the chalice of the Mass:

For in that Church, you see, as you have regularly been told, he performed the office of deacon; it was there that he administered the sacred chalice of Christ’s blood.

According to Christian history the Holy Grail is a relic that was sent by St Lawrence to his parents in northern Aragon. He entrusted this sacred chalice to a friend whom he knew would travel back to Huesca, remaining in the monastery of Saint John of Pena, core of spiritual strength for the emerging kingdom of Aragon. While the Holy Chalice's exact journey through the centuries is disputed, it is generally accepted by Catholics that the Chalice was sent by his family to this monastery for preservation and veneration. Historical records indicate that this chalice has been venerated and preserved by a number of monks and monasteries through the ages. Today the Holy Grail is venerated in a special chapel in the Catholic Cathedral of Valencia, Spain.
