Immanuel Kant
Kant was born on April 22, 1724 into a Prussian German family of Lutheran Protestant faith in Königsberg, East Prussia. Baptized 'Emanuel', he later changed his name to 'Immanuel' after learning Hebrew. He was brought up in a Pietist household that stressed religious devotion, humility, and a literal interpretation of the Bible. His education was strict, punitive and disciplinary, and focused on Latin and religious instruction over mathematics and science. Kant maintained Christian ideals for some time, but struggled to reconcile the faith with his belief in science. In his "Groundwork of the Metaphysic of Morals", he reveals a belief in immortality as the necessary condition of humanity's approach to the highest morality possible. However, as Kant was skeptical about some of the arguments used prior to him in defence of theism and maintained that human understanding is limited and can never attain knowledge about God or the soul, various commentators have labelled him a philosophical agnostic.
Dante Alighieri
Dante was born in Florence, Republic of Florence, present-day Italy. The exact date of his birth is unknown, although it is generally believed to be around 1265. This can be deduced from autobiographic allusions in the "Divine Comedy." Its first section, the "Inferno," begins, ""Nel mezzo del cammin di nostra vita"" ("Midway upon the journey of our life"), implying that Dante was around 35 years old, since the average lifespan according to the Bible (Psalm 89:10, Vulgate) is 70 years; and since his imaginary travel to the netherworld took place in 1300, he was most probably born around 1265. Some verses of the "Paradiso" section of the "Divine Comedy" also provide a possible clue that he was born under the sign of Gemini: "As I revolved with the eternal twins, I saw revealed, from hills to river outlets, the threshing-floor that makes us so ferocious" (XXII 151–154). In 1265, the sun was in Gemini between approximately May 11 and June 11 (Julian calendar).
