Why are there anachronistic elements in Anouilh's Antigone?

Firstly, it's important to establish what exactly an anachronism is:anachronism: something appropriate to a time period other than the one it exists inIn other words, if something is anachronistic, it is out of place either because it is too old-fashioned or too modern. Anouilh uses this technique often in Antigone - Antigone's "petite pelle", "les cigarattes" of Polynice or "les cirés noirs" worn by the guards. Despite the fact that this is a play occurring in the times of Ancient Greece, Anouilh deliberately chooses to include modern anachronistic elements - but why?One of the most important anachronisms are the uniforms (les cirés noirs) worn by the guards, reminiscent of the uniforms worn by the Gestapo - this brings to mind WWII and the Occupation. One possibility is that Anouilh uses this ancient tale to comment on the contemporary horrors of war, and subtly indicates this to the audience using visual clues. We can use part of this theory to explain all the other anachronisms - Anouilh includes them to remind the audience that this is not simply a retelling of an Ancient Greek fable, but a story that remains relevant across all time periods - the modern elements remind us that this story could happen at any time.
