The Christian Greek Scriptures make a number of references to Roman centurions. The army officer who oversaw Jesus’ execution held that rank, as did Cornelius, the first Gentile convert to Christianity. The officer who was to oversee the apostle Paul’s scourging and Julius, who escorted Paul to Rome, were also centurions.​—Mark 15:39; Acts 10:1, footnote; 22:25; 27:1.

A centurion normally commanded a century, which consisted of between 50 and 100 foot soldiers. His duties included training and disciplining his men, inspecting their clothes and equipment, and commanding them during deployments.

The rank of centurion was the highest that an ordinary soldier could reach. Those who filled this office were career soldiers who had to be good leaders. The discipline and efficiency of the Roman military machine depended on them. According to one source, centurions “were often the most experienced and best-informed men in the army.”

Unlike the glass mirrors of today, mirrors in Bible times were generally made of metal that was highly polished​—usually bronze, but possibly also copper, silver, gold, or electrum. The first mention of mirrors in the Bible is in connection with the construction of the tabernacle, Israel’s first center of worship. Women contributed mirrors for the fabrication of a sacred copper basin and its stand. (Exodus 38:8) Presumably, the mirrors would have to be melted down to be used for that purpose.

Mirrors recovered from archaeological excavations in and around Israel have usually been found with jewelry and other items of feminine adornment. Typically, those mirrors were circular in shape, with an ornamented wood, metal, or ivory handle, which was frequently shaped like a female figure. The mirror’s unpolished face was usually left unadorned.

The reflecting ability of ancient mirrors was limited compared to that of today’s glass mirrors. This likely explains what the apostle Paul was referring to when he said: “Now we see in hazy outline by means of a metal mirror.”​—1 Corinthians 13:12.
