Problem: In the 1500s, Paracelsus was probably the first to criticize Galen publicly. Also in the 16th century, scientist and artist Leonardo da Vinci compared metabolism to a burning candle. Leonardo did not publish his works on this subject, but he was not afraid of thinking for himself and he definitely disagreed with Galen. Ultimately, 16th century works of Andreas Vesalius, sometimes called the father of modern medicine, overturned Galen's ideas. He was followed by piercing thought amalgamated with the era's mysticism and religion sometimes fueled by the mechanics of Newton and Galileo. Jan Baptist van Helmont, who discovered several gases such as carbon dioxide, performed the first quantitative experiment. Robert Boyle advanced chemistry. Sanctorius measured body weight. Physician Herman Boerhaave modeled the digestive process. Physiologist Albrecht von Haller worked out the difference between nerves and muscles.
Which famous artist did not agree with Galen's theories?

Answer: Leonardo da Vinci


Problem: The biographical tradition asserts that Virgil began the hexameter Eclogues (or Bucolics) in 42 BC and it is thought that the collection was published around 39–38 BC, although this is controversial. The Eclogues (from the Greek for "selections") are a group of ten poems roughly modeled on the bucolic hexameter poetry ("pastoral poetry") of the Hellenistic poet Theocritus. After his victory in the Battle of Philippi in 42 BC, fought against the army led by the assassins of Julius Caesar, Octavian tried to pay off his veterans with land expropriated from towns in northern Italy, supposedly including, according to the tradition, an estate near Mantua belonging to Virgil. The loss of his family farm and the attempt through poetic petitions to regain his property have traditionally been seen as Virgil's motives in the composition of the Eclogues. This is now thought to be an unsupported inference from interpretations of the Eclogues. In Eclogues 1 and 9, Virgil indeed dramatizes the contrasting feelings caused by the brutality of the land expropriations through pastoral idiom, but offers no indisputable evidence of the supposed biographic incident. While some readers have identified the poet himself with various characters and their vicissitudes, whether gratitude by an old rustic to a new god (Ecl. 1), frustrated love by a rustic singer for a distant boy (his master's pet, Ecl. 2), or a master singer's claim to have composed several eclogues (Ecl. 5), modern scholars largely reject such efforts to garner biographical details from works of fiction, preferring to interpret an author's characters and themes as illustrations of contemporary life and thought. The ten Eclogues present traditional pastoral themes with a fresh perspective. Eclogues 1 and 9 address the land confiscations and their effects on the Italian countryside. 2 and 3 are pastoral and erotic, discussing both homosexual love (Ecl. 2) and attraction toward people of any gender (Ecl. 3). Eclogue 4, addressed to Asinius Pollio, the so-called "Messianic Eclogue" uses the imagery of the golden age in connection with the birth of a child (who the child was meant to be has been subject to debate). 5 and 8 describe the myth of Daphnis in a song contest, 6, the cosmic and mythological song of Silenus; 7, a heated poetic contest, and 10 the sufferings of the contemporary elegiac poet Cornelius Gallus. Virgil is credited[by whom?] in the Eclogues with establishing Arcadia as a poetic ideal that still resonates in Western literature and visual arts and setting the stage for the development of Latin pastoral by Calpurnius Siculus, Nemesianus, and later writers.

Problem: Within the world's Jewish population there are distinct ethnic divisions, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions. An array of Jewish communities was established by Jewish settlers in various places around the Old World, often at great distances from one another, resulting in effective and often long-term isolation. During the millennia of the Jewish diaspora the communities would develop under the influence of their local environments: political, cultural, natural, and populational. Today, manifestations of these differences among the Jews can be observed in Jewish cultural expressions of each community, including Jewish linguistic diversity, culinary preferences, liturgical practices, religious interpretations, as well as degrees and sources of genetic admixture.
