Answer:
It is the rigid body language that reflects Creon's status as king in "Antigone" by Sophocles (495 B.C.E. - 405 B.C.E.).
Specifically, Theban King Creon is determined and focused in his kingship. He lets no impact, opinions or precedents guide or influence him and his laws. The rigid, uncompromising, unyielding stance that he assumes physically and verbally reflect the narrow and stubborn focus of his kingship as a newly ascended king who remains unfamiliar with the give and take, the ups and downs implicit in any rule over time.
