In Early Medieval Europe first view, there is a review of the Companion by Mark Vessey:

– impeccably edited
– a work of reference which in the clarity and density of its coverage of a relatively compact oeuvre achieves a comprehensiveness scarcely conceivable for more historically influential figures
– speak[s] eloquently both for our own time and for what its authors agree in seeing as its subject’s mode of existence in his
– Sidonius has got the Companion he deserved.
