The staurogram (⳨), also monogrammatic cross or tau-rho,[1] is a ligature composed of a superposition of the Greek letters tau (Τ) and rho (Ρ).
The symbol is of pre-Christian origin. It is found on copper coins minted by Herod I in 37 BC, interpreted as a tr ligature representing trikhalkon indicating the coin value.[2]
The staurogram was first used to abbreviate stauros (σταυρός), the Greek word for cross, in very early New Testament manuscripts such as 𝔓66, 𝔓45 and 𝔓75, almost like a nomen sacrum, and may visually have represented Jesus on the cross.[3]
The Tau-Rho as a Christian symbol outside its function as nomen sacrum in biblical manuscripts appears from c. the 4th century, used as a monogramma Christi alongside the Chi-Rho and other variants, spreading to Western Europe in the 5th and 6th centuries.[4]
Ephrem the Syrian (4th century) discusses a Christian symbol, apparently combining the Tau-Rho with Alpha and Omega placed under the left and right horizontal arms of the Tau. Ephrem says that the Tau represents the cross of Jesus (prefigured by the outstretched hands of Moses in Exodus 17:11), the Alpha and Omega signify that the crucified Christ is "the beginning and end", and the Rho, finally, signifies "Help" (βοήθια [sic]; classical spelling: βοήθεια), because of the numerological value of the Greek word being 100, represented by Rho as a Greek numeral.[5]
The two letters tau and rho can be found separately (not in ligature) as symbols already on early Christian ossuaries.[6] Tertullian (Contra Marcionem 3.22) explains the Tau as a symbol of salvation by identification with the sign which in Ezekiel 9:4 was marked on the forehead of the saved ones.[3] The rho by itself can refer to Christ as Messiah because Abraham, taken as a symbol of the Messiah, generated Isaac according to a promise made by God when he was one hundred years old, and 100 is the value of rho.[6]: 158
The staurogram is encoded by Unicode in the Coptic block, at U+2CE8 ⳨ COPTIC SYMBOL TAU RO, and as of Unicode 7.0 (2014) also in the Ancient Symbols block, at U+101A0 𐆠 GREEK SYMBOL TAU RHO. The Coptic block has a ligature of the full word σταυρός, where the τρ is represented by the staurogram, and two lunate sigmas are attached to either side of the tau's horizontal bar, at U+2CE7 ⳧ COPTIC SYMBOL STAUROS.

The staurogram (⳨), also monogrammatic cross or tau-rho, is a ligature composed of a superposition of the Greek letters tau (Τ) and rho (Ρ).
The Chi Rho (☧, English pronunciation KY-ROH; also known as chrismon) is one of the earliest forms of the Christogram, formed by superimposing the first two (capital) letters—chi and rho (ΧΡ)—of the Greek ΧΡΙΣΤΟΣ (rom: Christos) in such a way that the vertical stroke of the rho intersects the center of the chi. The Chi Rho symbol was used by the Roman Emperor Constantine the Great (r. 306–337 AD) as part of a military standard (vexillum). Constantine's standard was known as the Labarum. Early symbols similar to the Chi Rho were the Staurogram (⳨) and the IX monogram (). Although formed of Greek characters, the device (or its separate parts) is frequently found serving as an abbreviation in Latin text, with endings added appropriate to a Latin noun, thus XPo, signifying Christo, "to Christ", the dative form of Christus, or χρ̅icola, signifying Christicola, "Christian", in the Latin lyrics of Sumer is icumen in.

Eusebius of Caesarea (c. AD 260/265 – 30 May AD 339), also known as Eusebius Pamphilius, was a historian of Christianity, exegete, and Christian polemicist from the Roman province of Syria Palaestina. In about AD 314 he became the bishop of Caesarea Palaestina. Together with Pamphilus, Eusebius was a scholar of the biblical canon and is regarded as one of the most learned Christians during late antiquity. He wrote the Demonstrations of the Gospel, Preparations for the Gospel and On Discrepancies between the Gospels, studies of the biblical text. His work Onomasticon is an early geographical lexicon of places in the Holy Land mentioned in the Bible. As "Father of Church history" (not to be confused with the title of Church Father), he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs. He also produced a biographical work on Constantine the Great, the first Christian Roman emperor, who was Augustus between AD 306 and AD 337.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
