AbstractLeonard Horner (1785–1864) was a pioneer in the study of loess. His 1836 paper on the geology of Bonn contained detailed descriptions of loess in the Rhine valley. He identified and presented loess as an interesting material for geological study. He investigated loess in the crater of the Rodderberg with Charles Lyell in 1833. He presented the first significant paper on loess in Britain in 1833, but it was not published until 1836. With the assistance of G.A. Goldfuss and J.J. Noegerath he conducted early studies of the Siebengebirge and published the first geological map of the region, and the first picture of loess, at Rhondorf by the Drachenfels. He became the eleventh person to be included in the list of loess scholars which Charles Lyell published in volume 3 of the Principles of Geology. These were Leonhard, Bronn, Boue, Voltz, Steininger, Merian, Rozet, Hibbert in 1833, Noeggerath, von Meyer in 1835, Horner in 1837. Horner arrived after the publication of his studies on the loess at Bonn in 1836.

Abstract The two critical books, launching the study and appreciation of loess, were ‘Charakteristik der Felsarten’ (CdF) by Karl Caesar von Leonhard, published in Heidelberg by Joseph Engelmann, in 1823-4, and ‘Principles of Geology’ (PoG) by Charles Lyell, published in London by John Murray in 1830-3. Each of these books was published in three volumes and in each case the third volume contained a short piece on loess (about 2-4 pages). These two books are essentially the foundations of loess scholarship. In CdF Loess [Loefs] was first properly defined and described; section 89 in vol. 3 provided a short study of the nature and occurrence of loess, with a focus on the Rhine valley. In PoG there was a short section on loess in the Rhine valley; this was in vol.3 and represents the major dissemination of loess awareness around the world. A copy of PoG3 (Principles of Geology vol. 3) reached Charles Darwin on the Beagle in Valparaiso in 1834; worldwide distribution. Lyell and von Leonhard met in Heidelberg in 1832. Von Leonhard and Heinrich Georg Bronn (1800-1862) showed Lyell the local loess. These observations provided the basis for the loess section in PoG3. Lyell acknowledged the influence of his hosts when he added a list of loess scholars to PoG; by the 5th edition in 1837 the list comprised H.G. Bronn, Karl Caesar von Leonhard (1779-1862), Ami Boue (1794-1881), Voltz, Johann Jakob Noeggerath (1788-1877), J. Steininger, P. Merian, Rozet, C.F.H. von Meyer (1801-1869), Samuel Hibbert (1782-1848) and Leonard Horner (1785-1864); a useful list of loess pioneers. The loess is a type of ground that has only recently been established, and it seems, the peculiarity of the Rhine region, and of a very general but inconsistent spread.” H.G. Bronn 1830

Principles Of Geology

AbstractCharles Lyell, on his way to becoming a famous geologist, married Mary Horner in Bonn in July 1832; volume 3 of his ‘Principles of Geology’ was published by John Murray in London in May 1833. Between these two dates Lyell encountered the loess of the Rhine valley. The loess impressed Lyell and he included mentions of it in the Principles, first in 1833 and then, with some revised ideas, in volume 4 of the 4th edition published in 1835. Twelve editions of the Principles were published between 1830 and 1875 and it became one of the most important works in the development of geology, and made a major contribution to the worldwide spread of loess awareness. It is possible that Lyell was drawn to the loess because of its high molluscan content, he was particularly attracted to the study of shells.

The Way

This chapter and the next one cover the way in which geology came to be a science in its own right, spanning the early centuries of geology. Lives of crucial individual scientists from the sixteenth century to the beginning of the twentieth century are discussed by relating the stories and discoveries of each, commencing with Leonardo da Vinci and continuing with the European geologists, including Nicholaus Steno, Abraham Werner, James Hutton, Charles Lyell, and early fossilists such as Etheldred Benet. Steno, Werner, Hutton and Lyell, and other early geologists revealed and wrote about the basic principles of geology, painstakingly untangling and piecing together the threads of the Earth’s vast history. They made sense of jumbled sequences of rocks, which had undergone dramatic changes since they were formed, and discerned the significance of fossils, found in environments seemingly incongruous to where the creatures once lived, as ancient forms of life. They set the stage for further research on the nature of the Earth and life on it, providing subsequent generations of geologists and those who study the Earth the basis on which to refine and flesh out the biography of the Earth.

Eifel Region

Abstract Charles Lyell made a geological excursion to the Eifel region in Germany in July 1831. He went to examine volcanic rocks and volcanic landscapes. He discussed this outing with Mary Somerville and Samuel & Charlotte Hibbert. It is possible that he observed loess in the Eifel. It is hoped that his Eifel notebook is with the Lyell papers at Kinnordy and that it may be transcribed and published. Lyell spread the word on loess; Von Leonard invented it and Horner enthused about it but Lyell disseminated the essential idea of loess. There is (so far) no clear evidence that Lyell saw and appreciated loess in the Eifel region in 1831. This suggests that his first real encounter with the loess (ground or concept) was in the discussions with the Hibberts in September 1831. He certainly had substantial (reported) encounters in 1832, and was definitely interested by the time of the publication of the Principles of Geology vol. 3 in 1833.

Charles Lyell’s Principles of Geology, the Geological Sublime, and the Romantic Theatre

Viewing Position

Across the three volumes of his influential Principles of Geology (1830–33), Charles Lyell demonstrates that the scale of earth history is out of all proportion to human temporality. Lyell makes the case that geologists should assume a viewing position outside the drama of geological action. He repeatedly represents this distance through the figure of the theatre, invoking Romantic critiques of theatrical naturalism that aligned with developments in natural philosophy. At the same time, Lyell deployed technologies from the contemporary stage in his public lectures, and in personal correspondence, he reveals promiscuous tastes across genres, forms and sites of performance. Ultimately, I argue, these apparent inconsistencies point to the role of his subjectivity in a project that is deeply ambivalent about human points of view.

Short Time

Of all geological questions, perhaps that of the Antiquity of Man is the most popular. Nor is it one on which geologists have been rash or hasty in advancing new ideas; quite the reverse: they have lagged behind the evidence. In the “Principles of Geology,” one of the most instructive chapters is that in which the author treats of the progress of Geology. Therein Sir Charles Lyell has shown how the science had been retarded for three hundred years by men's reluctance to admit such a simple and obvious matter as the marine origin of stratified rocks, owing to a fixed idea that the world had come into being a short time since in much the same state as it appears to-day. Yet the illustrious author of the “Principles of Geology” let pass for thirty years the evidence that Man was contemporaneous with the extinct Pleistocene mammalia.
