to touch her while he's running to make her fertile
Caesar has just returned and there is a massive celebration dedicated to him. This includes some sportive competitions which Antony is participating in. He is running in a race or "Lupercal" and the Romans believed that touching a competitor could make a woman fertile by touching her before they start, which is what Caesar tells his loyal friend to do.
So then everyone knows that Antony have Caesar's permission to touch Calpurnia (Caesar's wife).
Stand in front of a Calphurnia to cure her inability to have children.
Caesar wanted Antony to touch Calpurnia, because the touch of a running Roman man would prevent barrenness. In other words, it would make Calpurnia susceptible to becoming pregnant and eventually giving birth to a child. Caesar was hoping for an heir to his throne in the event that he died.
Antony's touch can make Calphurnia fertile.
Julius Caesar asks Marc Antony to touch his wife, Calpurnia to cure her from being sterile (unable to bare children)
Your question may be unclear. However, Caesars wife Calpurnia, was unable to have children. Caesar told Anthony, 'before you go, touch Calpernia, people say that if you touch an infertile woman at festival time she will be freed of infertility'
Caesar asks Mark Antony to touch Calpurnia with the leather thong in the hopes that it will cure her infertility. In ancient Roman beliefs, being touched by the thong during the Lupercalia festival was thought to promote fertility and ensure safe childbirth. Caesar's gesture reflects his desire to have an heir and continue his bloodline.
This quote from Shakespeare's "Julius Caesar" suggests that when the elders seek blessings from a woman like Calpurnia, barren women touched by her may believe they can overcome their infertility and have children. It reflects a belief in the power of touch to bring about positive change or fertility in women struggling to conceive.
In Julius Caesar, "shake off their sterile curse" means to be rid of their inability to have children. Caesar believes that if Antony touches Calpurnia during the Lupercal race, it will help her become fertile.
Marc Antony paraded himself around Rome. He had a touch of the showman in him, and during the time when he was Caesar's Master of the Horse, he paraded himself around Rome with his actor friends and his actress mistress causing a great scandal to the straitlaced Romans. Caesar was not amused.
The first two Acts of Julius Caesar are centred on the feast of Lupercalia, an ancient feast held in February when young men ran naked through the streets and struck women and girls with sticks. This was a fertility rite. In the play, Antony is shown as running this race, and Caesar asks him to touch his wife Calpurnia. In the play Shakespeare as usual compresses events, having the Lupercalia end on March 14 (just as he compresses the year between the battle of Munda and the assassination)
