Final answer:
The similarity lies in the depiction of Richard's distress in both the text and artwork, while the difference centers on the presence of self-love in the text as opposed to the portrayal of fear and isolation in the artwork.
Step-by-step explanation:
A similarity between Shakespeare's Richard III and William Hogarth's artwork depicting Act V is Richard's visible distress. In the play, Richard exclaims, "O coward conscience, how dost thou afflict me!" indicating his inner turmoil. Hogarth captures this torment visually, as Richard is shown with a fearful face and one hand in front of it, suggesting he is startled and distressed.
A difference lies in Richard's self-address; the play contains the line "Richard loves Richard, that is, I am I," showing his self-absorption. However, in Hogarth's depiction, there's a sense of isolation and fear rather than self-love, as no other characters are depicted to show reflection, and Richard is solely focused on the spectral apparitions rather than on himself.
