Crito
The dialogue takes place in Socrates' prison cell, where he awaits execution. He is visited before dawn by his old friend Crito, who has made arrangements to smuggle Socrates out of prison to the safety of exile. Socrates seems quite willing to await his imminent execution, and so Crito presents as many arguments as he can in order to persuade Socrates to escape. On a practical level, Socrates' death will reflect badly on his friends--people will think they did nothing to try to save him. Also, Socrates should not worry about the risk or the financial cost to his friends; these they are willing to pay, and they have also arranged to find Socrates a pleasant life in exile. On a more ethical level, Crito presents two more pressing arguments: first, if he stayed, he would be aiding his enemies in wronging him unjustly, and would thus be acting unjustly himself; and second, that he would be abandoning his sons and leaving them without a father.
The Death of Socrates
David uses color to highlight the emotion in this painting. The shades of red are more muted on the edges of the painting and become more vibrant in the center, culminating in the dark red robe of the man holding the cup of poison, generally taken as offering the cup to Socrates rather than receiving it after Socrates had consumed its contents. The only two serene men, Socrates and Plato, are garbed in a contrasting bluish-white. The more muted color scheme of this painting may be a response to critics of David's "Oath of the Horatii", who called his colors "garish".
