Philology is the study of language in written historical sources; it is a combination of literary studies, history and linguistics.

Classical philology is the philology of Greek and Classical Latin. Classical philology is historically primary, originating in European Renaissance Humanism, but was soon joined by philologies of other languages both European (Germanic, Celtic, Slavistics, etc.) and non-European (Sanskrit, Persian, Arabic, Chinese, etc.). Indo-European studies involves the comparative philology of all Indo-European languages.

Any classical language can be studied philologically, and indeed describing a language as "classical" is to imply the existence of a philological tradition associated with it.

Because of its focus on historical development (diachronic analysis), philology came to be used as a term contrasting with linguistics. This is due to a 20th-century development triggered by Ferdinand de Saussure's insistence on the importance of synchronic analysis, and the later emergence of structuralism and Chomskian linguistics with its emphasis on syntax.

The Brothers Grimm (German: Brüder Grimm or Die Gebrüder Grimm), Jakob Grimm (January 4, 1785 – September 20, 1863) and Wilhelm Grimm (February 24, 1786 – December 16, 1859), were German academics, linguists, cultural researchers, and authors who together collected folklore. They are among the most well-known storytellers of European folk tales, and their work popularized such stories as "Cinderella", "The Frog Prince" (Der Froschkönig), "Hansel and Gretel" (Hänsel und Gretel), "Rapunzel", "Rumpelstiltskin" (Rumpelstilzchen), and "Snow White" (Schneewittchen). Their first collection of folk tales, Children's and Household Tales (Kinder- und Hausmärchen), was published in 1812.

The brothers spent their formative years first in the German town of Hanau and then in Steinau. Their father's death in 1796, about a decade into their lives, caused great poverty for the family and affected the brothers for many years. They attended the University of Marburg where historian and jurist Friedrich von Savigny spurred their interest in philology and Germanic studies—a field in which they are now considered pioneers—and at the same time developed a curiosity for folklore, which grew into a life-long dedication to collecting German folk tales.
