This post didn't ring true to me, so I crossed referenced a few sources. Turns out, the below claim is false.
First Century depictions in the Greek catacombs were simple crosses known as Staurogram
Yes, early Christian depictions, particularly the staurogram (a tau-rho ligature, combining Greek 'T' and 'P'), served as simple crosses,
representing Jesus on the cross in manuscripts and art from the 2nd-4th centuries, predating more complex crucifixions and signifying the crucifixion itself, showing early Christian reverence for the cross as a core symbol.
The statement is partially accurate but contains some inaccuracies regarding timing and location. The staurogram (⳨ or ) is indeed an early Christian symbol combining the Greek letters tau (Τ) and rho (Ρ). It forms a monogram that abbreviates words like "stauros" (cross) or "stauroō" (to crucify)
. When superimposed, it creates a looped cross shape that scholars interpret as a pictorial representation of a crucified figure (the tau as the crossbeam and upright, the rho loop as a head). This makes it one of the earliest visual references to the crucifixion of Jesus, appearing in New Testament manuscripts like Papyrus 66, 75, and 45 from around 175–225 CE.
Yes, the staurogram (ΤΡ), formed from Greek Tau (Τ) and Rho (Ρ), was an early Christian symbol, appearing in 2nd-century manuscripts as an abbreviation for stauros (cross) and
visually representing Jesus on the cross, predating explicit crucifixion images and appearing in catacomb-era art, though often alongside other symbols like the fish and Good Shepherd, becoming prominent by the 4th century in sarcophagi and inscriptions.
