Here are three more showing how some were crushed to death, had their skin torn off their body with a pitchfork-looking device, or were boiled to death.
And here's a little on the good and holy Deacon, St. Stephen gleaned from the Catholic Encyclopedia:
One of the first deacons and the first Christian martyr; feast on 26 December. In the Acts of the Apostles the name of St. Stephen occurs for the first time on the occasion of the appointment of the first deacons (Acts 6:5). Dissatisfaction concerning the distribution of alms from the community's fund having arisen in the Church, seven men were selected and specially ordained by the Apostles to take care of the temporal relief of the poorer members. Of these seven, Stephen, is the first mentioned and the best known.
That he was pre eminently fitted for that work, his abilities and character, which the author of the Acts dwells upon so fervently, are the best indication. The Church had, by selecting him for a deacon, publicly acknowledged him as a man "of good reputation, full of the Holy Ghost and wisdom" (Acts 6:3). He was "a man full of faith, and of the Holy Ghost" (vi, 5), "full of grace and fortitude" (vi, 8); his uncommon oratorical powers and unimpeachable logic no one was able to resist, so much so that to his arguments replete with the Divine energy of the Scriptural authorities God added the weight of "great wonders and signs" (vi, 8). Great as was the efficacy of "the wisdom and the spirit that spoke" (vi, 10), still it could not bend the minds of the unwilling; to these the forceful preacher was fatally soon to become an enemy.
After preaching of the Apostles, Stephen was arrested, and dragged before the Sanhedrin, where he was accused of saying that "Jesus of Nazareth shall destroy this place [the temple], and shall change the traditions which Moses delivered unto us" (vi, 12 14). The accusation left him unperturbed and "all that sat in the council...saw his face as if it had been the face of an angel" (vi, 15).
Stephen's answer (Acts 7) was a long recital of the mercies of God towards Israel during its long history and of the ungratefulness by which, throughout, Israel repaid these mercies. This discourse contained many things unpleasant to Jewish ears; but the concluding indictment for having betrayed and murdered the Just One whose coming the Prophets had foretold, provoked the rage of an audience made up not of judges, but of foes. When Stephen "looking up steadfastly to heaven, saw the glory of God, and Jesus standing on the right hand of God", and said: "Behold, I see the heavens opened, and the Son of man standing on the right hand of God" (vii, 55), they ran violently upon him (vii, 56) and cast him out of the city to stone him to death. Stephen's stoning does not appear in the narrative of the Acts as a deed of mob violence; it must have been looked upon by those who took part in it as the carrying out of the law. According to law (Leviticus 24:14), or at least its usual interpretation, Stephen had been taken out of the city; custom required that the person to be stoned be placed on an elevation from whence with his hands bound he was to be thrown down. It was most likely while these preparations were going on that, "falling on his knees, he cried with a loud voice, saying: "Lord, lay not this sin to their charge" (vii, 59). Meanwhile the witnesses, whose hands must be first on the person condemned by their testimony (Deuteronomy 17:7), were laying down their garments at the feet of Saul, that they might be more ready for the task devolved upon them (vii, 57). The praying martyr was thrown down; and while the witnesses were thrusting upon him "a stone as much as two men could carry", he was heard to utter this supreme prayer: "Lord Jesus, receive my spirit" (vii, 58). Little did all the people present, casting stones upon him, realize that the blood they shed was the first seed of a harvest that was to cover the world.
