children of Aesculapius
Latin form of the name Asklepios, a Greek hero later revered as a god of medicine and healing. He was the son of Apollo and a mortal woman named Coronis, but became immortal himself after being killed by Zeus for reviving the dead with his medicinal skill, something only a god should have been able to do. Trollope refers to Dr. Thorne’s fellow doctors as the “children of Aesculapius.” [JM 2005]

Latin, “medical material.” Dr. Thorne earns the disdain of his medical colleagues by actually making medicine rather than just experimenting with materia medica; he is seen as being more concerned with money than with the intellectual side of his career. [JM 2005]
toga of silence
Trollope uses the quintessential garment of the Roman citizen to symbolize a dignified resistance to public attack. Dr. Fillgrave, however, is unable to stayed wrapped in a toga of silence, and he engages in a public struggle with Dr. Thorne, conducted through newspaper letters. [JM 2005]
The image may recall a detail from Plutarch’s account of the death of Caesar: once he realized that Brutus was one of the attackers, he covered himself and submitted. See the gloss in the commentary for Chapter 15 of The Warden. [RR 2011]

A genius for a Roman would have been a minor divinity charged with the guardianship of a person or place. Mary Thorne is to be the genius of Dr. Thorne’s home, newly and pleasantly refurbished in preparation for her coming. [JM 2005]
drops falling, if they fall constantly, will bore through a stone
In Latin: Gutta cavat lapidem. Mr. Gresham and Dr. Thorne are fast friends, despite Lady Arabella’s disdain for the doctor; but over time she manages to weaken their relationship, as drops hollow stone. [JM 2005]
