I want to know the answer to the following question:
In which work did he refer to Constantius as a precursor of the Antichrist?
All the background I'm provided with is that "Constantius's persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist.". Is that enough to answer the question?
Answer: yes
