A quarter of a century later, Rembrandt was commissioned to paint a portrait of a dissection by Doctor Johan Deyman, Tulp's successor as Amsterdam's Chief Anatomist. Hung alongside The Anatomy Lesson of Dr Tulp , in the city's Anatomical Theatre, The Anatomy Lesson of Dr. Deyman (1656, Rijksmuseum) was later badly damaged by fire in 1723, and only a central fragment survives. More reflective of the reality of the post-mortem, it shows Deyman in the process of dissecting the brain while the university lecturer Gysbrecht Calkoen holds the skull-cap in his hand. The work is noted, in particular, for its foreshortening, reminiscent of The Dead Christ (1480s, Pinacoteca di Brera, Milan) by Andrea Mantegna. A modern example of the dissection genre is the wonderful Gross Clinic (1875; Philadelphia Museum of Art) by Thomas Eakins .
Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
Finally, Frye proposes an anagogic phase wherein a symbol is treated as a monad. The anagogic level of medieval allegory treated a text as expressing the highest spiritual meaning. For example, Dante's Beatrice in the Divine Comedy would represent the bride of Christ. Frye makes the argument that not only is there a lateral connection of archetypes through intertextuality, but that there is a transcendent almost spiritual unity within the body of literature. Frye describes the anagogic in literature as "the imitation of infinite social action and infinite human thought, the mind of a man who is all men, the universal creative word which is all words."
