For western scholars/thinkers, this conjures images of rope/neck... 

Scholars were SURE that this was "crucifixion" AND was a imposed on Israel by the Romans

However,  archaeological evidence pictures the cross quite differently than Christian tradition...

And, the upright post was probably a rooted olive tree with the branches stripped away...

Deuteronomy 21:22-23

"...if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree: His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance."

But, the Book of Mormon clarifies this ancient, 

Mosaic law was for the EXECUTION of "traitors"...

3 Nephi 4:28

And their leader [Gaddianton Robbers], Zemnarihah, was taken and hanged upon a tree, yea, even upon the top thereof until he was dead. And when they had hanged him until he was dead they did fell the tree to the earth, and did cry with a loud voice, saying: May the Lord preserve his people in righteousness and in holiness of heart, that they may cause to be felled to the earth all who shall seek to slay them because of power and secret combinations, even as this man hath been felled to the earth.

Which was NOT known until 1960's, when the Dead Sea Temple scroll was translated into English...

Which provides great insights to key biblical verses

Joshua 8:29

And the king of Ai he hanged on a tree until eventide: and as soon as the sun was down, Joshua commanded that they should take his carcase down from the tree, and cast it at the entering of the gate of the city, and raise thereon a great heap of stones, that remaineth unto this day.

Joshua 10:26

And afterward Joshua smote them, and slew them, and hanged them on five trees: and they were hanging upon the trees until the evening.

Acts 5:30

The God of our fathers raised up Jesus, whom ye slew and hanged on a tree.

Acts 10:39

And we are witnesses of all things which [Jesus] did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree

Acts 13:29

And when they had fulfilled all that was written of him, they took him down from the tree, and laid him in a sepulchre.

 The Greek terms for “cross” and “crucify”can and do at times simply refer to the idea of being affixed to a tree and that the Romans sometimes used trees in their crucifixions. All these observations as a whole prevent us from concluding that Christ was crucified on a wooden post.  – Ernest L. Martin, The Secrets of Golgatha, p. 193-194

and, insight as to the actual nature of Judas's death

2 Samuel 17:23

"...when Ahithophel saw that his counsel was not followed, he saddled his ass, and arose, and gat him home to his house, to his city, and put his household in order, and hanged himself, and died"

Interestingly, this practice also appears at three Mayan Codices... 

all victims have also been STABBED in the side.

And at one ruin... Kabah, Mexico

And, in Japan, of all places...

“O my fellow-prisoners! ˹The first˺ one of you will serve wine to his master, and the other will be crucified and the birds will eat from his head. The matter about which you inquired has been decided.”
