Sara Parvis 
Marcellus of Ancyra and the Lost Years of the Arian Controversy 325-345 [PDF ebook] 

Is it true, as has often been claimed in recent years, that there was no real controversy in the period immediately following the Council of Nicaea? Sara Parvis, in this lively and meticulous study, argues not. She shows that the two opposing parties which had formed in support of Alexander of Alexandria and Arius in the years before Nicaea continued their activities afterwards, targeting one another with ruthless zeal at a series of synods which may look neutral butare revealed to be demonstrably partisan. Only the deaths of all the original party leaders except Marcellus of Ancyra, and the rise of Athanasius, broke the impasse which followed and allowed new political and theological configurations to form.
