Paolo Mastandrea writes a review of the Companion in the Classical Review, FirstView 12 August 2021. He values the volume as ‘a well-structured and accessible text that does what older friends [i.e., many other companion volumes] should do: to assist the non-specialist or less-experienced scholar’. He signals the odd ‘fundamental contribution’ and ‘some fascinating surprises’. He thinks Sidonius’ Christian inclinations as an author should not be overstated and points out a number of (indirect) borrowings from Ennius.
