His name is given as "Plakentios" in Riedinger and Mansi, "Placentinus" in the Lib. Pont. Plakentios 1 (i.e. Placentius) was bishop of Velitrae in Campania; he was one of the hundred and twenty-five Western bishops who attended the council of Rome at Easter 680, and who subscribed the decree condemning monotheletism: Riedinger II 2. 144, lines 4-6 (= Mansi XI 301- 302) (Πλακέντιος ἐλάχιστος ἐπίσκοπος τῆς ἁγίας ἐκκλησίας Βελλικέρνης ἐπαρχίας Καμπανίας; the old Latin version printed in Riedinger II 2. 145, lines 4-6 identifies his see as "ecclesiae Belliternensis prouinciae Campaniae"). In 682 he was one of the three bishops who consecrated Leo II (Leo 16) as bishop of Rome, during a vacancy in the see of Albanum: Lib. Pont. 82.7 ("a tribus episcopis, id est Andrea Hostense, Iohanne Portuense et Placentino Belliternense, pro eo quod Albanensis ecclesia episcopum minime habuit"). Possibly the same three bishops (no names are recorded but the sees were the same) consecrated John V (Ioannes 31) as bishop of Rome in 685: Lib. Pont. 84. 3. See Andreas 6 and Ioannes 21.
