The AD33 crucifixion detail in Judea

[Nathan Ross]

One did not need to nail a victim to a cross, using ropes was also sufficient,

Sure but archeologists found an example of a jew crucified with nails dating to the first century (a young man from a wealthy family c 70 CE).

Heliodorus, in Aethiopica, mentions that criminals in Egypt were crucified by tying rather than nailing to the cross. The implication is that this was an Egyptian practice, and that nails were used elsewhere.
