Ugh, since I cant think of anything dangerous that can stop Heracles for now, I will think of something difficult
Now that I have time to think, what will be dangerous for Heracles to kill or capture for when he returns...
Eurystheus did not accept Heracles's last labor because he had some assistance from Iolaus. But Eurystheus could not think of anything that was dangerous for him to defeat so he thought of something that just that was difficult to do.
I see it!
Eurystheus ordered Heracles to capture a beautiful deer called the Cerynean Hind. It took Heracles a full year to complete this task which gave Eurystheus time to think about something dangerous for Heracles to complete when he came back.
He's too fast!
The deer that Heracles was supposed to capture was a beautiful animal with golden horns, Artemis's favorite. The Cerynean Hind ran wild on the wooded hills and shady valleys of Arcadia.
Heracles went throughout half the hills of Greece to find this deer, wishing to capture it alive. Even though he never got tired from running, he could never catch the deer because of its speed.
Some nights, he would see a glint of light from the pale gold horns of the deer, but then it just ran away instantly. The deer avoided obstacles and nets like if it was being guided by Artemis.
Heracles realized he would never catch the deer on foot so he wounded it with an arrow then he finally captured it. As he was walking back in triumph, Artemis stopped him and asked how dare he harm her beautiful hind. Heracles begged for forgiveness then told her why he did what he did and she allowed him to complete his labor.
