In a new article on ‘The Poet Nemesianus and the Historia Augusta‘, centred on onomastics in the Life of Carus (JRS 2022, open access), Justin Stover and George Woudhuysen, in passing (fn. 4), advocate some renewed confidence in the hypothesis that Sidonius Apollinaris is reflected in the HA:

‘The argument of Domaszewski (Die Personennamen bei den Scriptores historiae Augustae, Heidelberg, 1918: 19, here), that Aurelius Apollinaris was inspired by Sidonius Apollinaris, who did write about the deeds of Carus (Carm. 23.88–96), has been treated with greater contempt than it perhaps deserves’.
