To marshal her forces against such an enemy as Lord Rufford
Arabella has become extremely concerned with her clothing and outward appearance. Arabella views her adornment as a sort of battle tactic and a way for her to seduce Lord Rufford. In book 14 of Homer’s Iliad, Hera attempts to seduce Zeus in order to undermine his schemes. Hera’s adornment of herself is likened to a man’s donning of armor for battle. Arabella’s pursuit of a marriage proposal is repeatedly presented as a feminine version of a military campaign. [KS & RR 2012]
