"... the volume overall is a great success and fully achieves its stated aims. The quality of the individual chapters is high, and many make important contributions. Each chapter includes a survey of recent work on its topic, and this, together with Kemezis’ masterly overview, makes the volume an admirable guide to the recent Dio explosion, to which it is itself a most valuable addition." - John Rich, in: BMCR 2025.07.42
"The volumes under discussion are invaluable contributions to the scholarship on Dio’s intellectual landscape, narrative technique, and theory of empire. (...) Brill’s Companion offers an exciting and up-to-date reflection of the complexity and sophistication of the debate, (...). Finally, what strikes the reader of these volumes as a whole is that all chapters are extremely well-written and well-edited." - Leanne Jansen, Department of Classics, Groningen University, in: "Literary Technique in the Roman History", Mnemosyne 78.3 (2025)
"Da qualche anno a questa parte si assiste a un curioso e per certi versi enigmatico fenomeno di “riscoperta” di Cassio Dione, con una crescita a dir poco tumultuosa e sovrabbondante della letteratura scientifica in materia [...]. Non si può dunque negare l’utilità di un volume complessivo – volutamente di ampio respiro – che possa fornire un orientamento aggiornato e affidabile sui risultati fin qui raggiunti dalla ricerca. In tal senso la scelta dei due studiosi quali responsabili del progetto è sicuramente azzeccata e quanto mai felice. [...] La visione d’insieme che si ricava dalla lettura di questo Companion to Cassius Dio è indubbiamente stimolante e ricca di spunti fecondi. Tutti i contributi sono di alto livello e suscitano un forte interesse; molti appaiono scritti con eleganza, alcuni riescono nella non facile impresa di proporre risultati nuovi e originali su questioni fin qui poco frequentate dalla critica. [...] In tal senso la raccolta di saggi di Madsen e Scott – la prima del suo genere dedicata interamente al colto senatore della Bitinia – dev’essere salutata con vivo favore perché viene a colmare un evidente vuoto editoriale, specialmente alla luce dell’enorme fioritura di studi dell’ultimo periodo. Tommaso Leoni, in: Bollettino di Studi Latini Anno LV - fascicolo II - Luglio-Dicembre 2025.
