That's interesting.... If one learns about the Roman catacombs and early Christian history within the context of the societies of Ancient Greeks, Ancient Romans, Mesopotamians, Assyrians, Acadians, Ancient Egyptians... IMO even showing the cross or crucifix is a privilege worth experiencing.
Personally, I know all about Nero (Roman emperor who executed many, including many Christians, the poor, his mother, his wife, atrociously SLAVES). The ancient Romans, Greeks, Mesopotamian, ect. all had among their wrongs,
repulsively SLAVES for thousands of years, child labor, a fixed ascribed at birth socioeconomic hierarchy, endless continuous and bloody warfare, women without
ANY rights, lifelong emperors who killed each other often, poor nonexistent healthcare, the sick elderly and disabled treated as trash, men who couldn't vote if they didn't own property, no education or literacy except for the privileged, and unequal brutal punishments skewed against the poorer classes.... I know of the
numerous roman emperors who persecuted Christians until Emperor Constantine 300 years later A.D. when they
finally let them worship in public.
During this entire 300 year devastation against humanity by humanity, Christians had to hide their crosses with other symbolic meanings which could "blend in" better with the paganistic Roman ruler's beliefs.
Here's a good website for information on the early Christian symbols seen in the catacombs from 30 A.D. - 313 A.D. <htt p: // w ww. jesuswalk. com / christian-symbols/> (remove ">" and "<" and paste into url)
"The Cross in Christian Art and Monuments
During the period of persecutions before Constantine I, we generally don't find the cross on monuments and catacomb sepulchres. It is nearly always disguised -- as an anchor [often the horizontal "stock" at the top reminded Christians of the cross], later a trident, or the mainmast of a ship.1 Other disguised forms of the cross include monograms such as what is called the St. Andrew's cross, in the shape of the Greek letter
chi." ...[Other examples of symbols are the good shepherd for JESUS, fish/Ichthus representing JESUS's name, peacocks, and doves for the Holy Spirit]
...Chi and Rho are the first two letters (
ΧΡ) of "Christ" in Greek
ΧΡΙΣΤΟΣ. (
Christos). Sometimes it is called the Monogram of Christ or Chrismon or Labarum. While it was used very early by persecuted Christians in the catacombs, when Constantine I was struggling to become emperor, he used the symbol at the front of his armies and was victorious (see below)
The Chi-Rho is often shown with the Greek letters Alpha (A) and Omega (lower case ώ or upper case Ω

, the first and last letters of the Greek alphabet.
Jesus refers to himself: "I am the Alpha and the Omega, the First and the Last, the Beginning and the End." (Revelation 22:13).
[it depicts]...the symbol of the Saviour's name, two letters indicating the name of Christ by means of its initial characters, the letter P being intersected by X in its centre...."
Here are some good videos about the early Christian art (and its symbolism for representing Jesus, God) in the Roman catacombs:

With this knowledge, IMO it is an absolute privilege to show the cross and crucifix in public, in light of the centuries it took to be able to show it by early Christians, and the horrendous treatment they had to endure under the Roman emperors. IMO Christians should also be loud and proud about their faith, spreading
Jesus's (God's) love for
ALL and His mercy (and His fight against the Ancient Roman/human ways of brutality! Jesus was God in human form (God's ultimate theophany - Jesus!
The Alpha and the Omega, the Beginning and the End!) showing us
the PERFECT and sinless example to live by! He was the "I AM" as in Exodus!).
