The origin of this name is still today quite uncertain. The theories include: A) From the Late Latin “Iūlius”, meaning “youth, youthful, juvenile”. B) A supreme god from the Latin and Proto Indo-European “*djew > iou-pater > Juppĭtĕr”. Jupiter is the King of the Gods and the God of sky and thunder in Roman Religion. C) From the Ancient Greek “Íoulos (ἴουλος)”, meaning “haired, bearded, downy-bearded”. The Roman and the standard meaning is “sacred to Jupiter”. The Gens Julia or Iulia was one of the most ancient Patrician families in ancient Rome. Members of the Gens attained the highest dignities of the state in the earliest times of the republic. Iūlius is the fifth month of the Roman calendar. The month was renamed in honor of Gaius Julius Caesar after his death and deification, as he was born in this month. In republican Rome, the month was formally known as Quintilis, "fifth”. July is the seventh month of the year in the Julian and Gregorian Calendars. 1) Julius Caesar (100–44 BC) was a Roman general, statesman, consul, and notable author of Latin prose. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Crassus, and Pompey formed a political alliance that was to dominate Roman politics for several years. 2) Saint Giulia Salzano (1846–1929) was the founder of the Congregation of the Catechetical Sisters of the Sacred Heart of Jesus in 1905. The feast day is traditionally celebrated on May 17.
