Charles Lyell's "Principles of Geology" of 1830 featured as its frontispiece a replication of di Jorio's illustration of the columns (shown above), and a detailed section discussing their significance. He strongly contested Daubeny's argument, and instead proposed slow and steady geological forces. Lyell wrote "That buildings should have been submerged, and afterwards upheaved, without being entirely reduced to a heap of ruins, will appear no anomaly, when we recollect that in the year 1819, when the delta of the Indus sank down, the houses within the fort of Sindree subsided beneath the waves without being overthrown." In 1832 the young Charles Darwin used Lyell's methods at the first landfall of the "Beagle" survey voyage, while considering evidence of land rising up at St. Jago. In his journal, Darwin dismissed Daubeny's argument, and wrote that he felt "sure at St Jago in some places a town might have been raised without injuring a house."
