As per rule 7, any additional context you want to convey about the art you're posting can be done in the body of the post or in the comments. What you're asking for is already allowed and encouraged.

His contemporaries alleged he had held his breath until he expired; although other accounts of his death say he had become ill from eating raw octopus;[44] or to have suffered an infected dog bite.[45] When asked how he wished to be buried, he left instructions to be thrown outside the city wall so wild animals could feast on his body. When asked if he minded this, he said, "Not at all, as long as you provide me with a stick to chase the creatures away!" When asked how he could use the stick since he would lack awareness, he replied: "If I lack awareness, then why should I care what happens to me when I am dead?"[46] To the end, Diogenes made fun of people's excessive concern with the "proper" treatment of the dead.
