This cross, latinate in shape has the ear like top right extension indicating it's connection to the Rho character. It has been attributed to the merging of the Chi-Rho symbol, together with the Latin Cross, which in turn probably originated from the Ankh or ancient egyptian symbol of eternal life, as witnessed by a bust from the Fayum http://en.wikipedia.org/wiki/Image:Coptic_bust.jpg), or the interchange of Ankh's and crosses on a tablet in the Coptic Museum, Cairo. This is a logical conclusion, as Christ was most likely crucifed on a Tau cross. This was the dominant form used by the Romans. as it is the quickest and cheapest method to create a suitable cross for execution. You merely have to get a soldier to nail a cross piece onto the top of an upright, rather than employ a carpenter to produce a mortice joint to create the typical Latin crucifix form.
Arius (AD 256 - 336), the founder of Arianism, was a pupil of Lucian, presbyter in Antioch, who apparently held very similar views but which, he did not promote publically, unlike Arius. "He (Arius) held a prominent position as presbyter in the Church of Alexandria when the Arian controversy with Bishop Alexander began (about 318) concerning the eternal deity of Christ and his equality with the Father (homoousia), which he denied, holding that Christ was of a different essence, and a creature of the Father, though created before the world."
Originating in Alexandria, Arianism developed some syncretic symbolism. I have already mentioned the Coptic cross, but also must mention the sun cross or equal armed cross. This was frequently modified by the Rho like adition on the top right of the upright.

The Ostrogoths, who had settled in Thrace after the battle of Adrianople (378 AD.) had a powerfull new leader in the mid 5th Century, Theoderic, who was made 'Master of the Soldiers' by the Eastern Roman Emperor, Zeno. The latter directed Theoderic to take his people to Northern Italy, to oust Odoacer, a Hun, who had become de facto King in that part of Italy. They left for Italy in 488 AD. and had captured Ravenna and killed Odoacer by 493 AD.Theoderic thus had made himself King of Italy, which he ruled from 493-526 AD.
Unfortunately for the Roman population of Ravenna, their captor, Theoderic, was a member of a group, which like all the Goths, had been converted to Christianity, in the 340's AD, by the missionary Bishop Ulfinus, who was Arian! Theoderic thus started building up an Arian clergy. The evidence from Ravenna consists of common Coptic Crosses on Sarcophigi, together with one unique occurrence on a Theoderic period building, recorded incorrectly as Theoderic's Palace. This is significant, as it ties the cross directly to Theoderic. Coptic Crosses are seen on numerous sarcophogi. found in the majority of the churches we visited. The problem is that they are dated styalistically and are commonly re-used. Dating them can be fraught, as few have any dedication inscriptions and where they do they commonly refer to a re-use.
Less than fifty years after his death, there came the final Gothic influx into Italy, in the form of the arrival of the Lombards, another Arian Christian group. There thus was all told probably more than a hundred years of Arian influence in Northern Italy.

'Theoderic's Palace'

Sarcophagus in the grounds of San Vitale, does the lid match the base,
it looks unlikely, base should probably look like the following picture!
The combination of a Coptic cross with a pair of sheep is a common format

Matching Lid & base from St. Francisco. Recorded as being created in thr 3rd century, lambs and 'Chrismon' added in the 6th and finally reused in the 18th Century!
Note the presence of the Alpha and Omega symbols attached to the limb
of the bottom cross.
