Ignatius was an early Christian writer and bishop of Antioch.

Epistle of Ignatius to the Romans
​
All the way from Syria to Rome I am fighting with wild beasts, by land and sea, night and day, chained as I am to ten leopards (I mean to a detachment of soldiers), who only get worse the better you treat them. But by their injustices I am becoming a better disciple, “though not for that reason am I acquitted.”
