Giovanni Battista (also Giambattista) Piranesi (4 October 1720 – 9 November 1778) was an Italian artist famous for his etchings of Rome and of fictitious and atmospheric "prisons" (Carceri d'Invenzione).

Piranesi was born in Mogliano Veneto, near Treviso, then part of the Republic of Venice. His brother Andrea introduced him to Latin and the ancient civilization, and later he studied as an architect under his uncle, Matteo Lucchesi, who was Magistrato delle Acque, a Venetian engineer who specialized in excavation.

From 1740 he was in Rome with Marco Foscarini, the Venetian envoy to the Vatican. He resided in the Palazzo Venezia and studied under Giuseppe Vasi, who introduced him to the art of etching and engraving. After his studies with Vasi, he collaborated with pupils of the French Academy in Rome to produce a series of vedute (views) of the city; his first work was Prima parte di Architettura e Prospettive (1743), followed in 1745 by Varie Vedute di Roma Antica e Moderna.

From 1743 to 1747 he sojourned mainly in Venice where, according to some sources, he frequented Giovanni Battista Tiepolo. He then returned to Rome, where he opened a workshop in Via del Corso. In 1748–1774 he created a long series of vedute of the city which established his fame. In the meantime Piranesi devoted himself to the measurement of many of the ancient edifices: this led to the publication of Antichità Romane de' tempo della prima Repubblica e dei primi imperatori ("Roman Antiquities of the Time of the First Republic and the First Emperors"). In 1761 he became a member of the Accademia di San Luca and opened a printing facility of his own. In 1762 the Campo Marzio dell'antica Roma collection of engravings was printed.

The term historical Jesus refers to scholarly reconstructions of the 1st-century figure Jesus of Nazareth. These reconstructions are based upon historical methods including critical analysis of gospel texts as the primary source for his biography, along with consideration of the historical and cultural context in which he lived.

The historical Jesus is believed to be a Galilean Jew who undertook at least one pilgrimage to Jerusalem, then part of Roman Judaea, during a time of messianic and apocalyptic expectations in late Second Temple Judaism. He was baptized by John the Baptist, whose example he may have followed, and after John was executed, began his own preaching in Galilee for only about two to three years prior to his death. He was an eschatological prophet and an autonomous ethical teacher. He told surprising and original parables, many of them about the coming Kingdom of God. Some scholars credit the apocalyptic declarations of the Gospels to him, while others portray his Kingdom of God as a moral one, and not apocalyptic in nature. He sent his apostles out to heal and to preach the Kingdom of God. Later, he traveled to Jerusalem where he caused a disturbance at the Temple. It was the time of Passover, when political and religious tensions were high in Jerusalem. The Gospels say that the temple guards (believed to be Sadducees) arrested him and turned him over to the Roman governor Pontius Pilate for execution. The movement he had started survived his death and was carried on by his brother James the Just and the apostles who proclaimed the resurrection of Jesus. After splitting with Rabbinic Judaism, it developed into Early Christianity.
