The mapped head was associated with phrenology from its earliest publications throughout the nineteenth century. It provided a useful map of the locations on the skull discussed in phrenological tracts.

This chart provides the "average," "full," "large," "very large," "moderate," "small," and "very small" sizes of the organs measured in each phrenological category.

Phrenology is important to list here not only because of its publication date—so close to that of Cruikshank’s own work—but also because it is characteristic of the larger corpus of phrenological tracts. Spurzheim’s third edition of this book was published in 1825 and was one of five books extracted from a larger work entitled The Phsyiognomical System.

The ruins of this votive chapel, built in the medieval period, are set against a dramatic, mountainous backdrop. In the aquatints depicting the ruins of Castle Abergavenny and Raglan Castle the mountains are pushed farther into the background. Furthermore, unlike the complex ruins that Gilpin typically depicts, this image features a man-made structure that is surprisingly simple.

This image of tourists before a view of Dunster Castle highlights the importance assigned to the interaction of persons with natural or constructed elements of the landscape in Romantic-era tourism. Gilpin’s inclusion of human figures in this view of Dunster Castle departs from the way in which he represents tours of the River Wye.
