Platon 13 was the father of pope John VII (Ioannes 228); presumably a Greek, like his son (who was "natione Grecus"): Lib. Pont. 88. 1. He is to be identified with Plato whose epitaph, composed by his son Ioannes 228, is extant and who died in 686: Epitaph (in Duchesne, Lib. Pont. I, p. 386, n. 1 = Marini, P. Dip., p. 368 = Rossi, Bull. 1867, p. 11 = Rossi, ICVR II 442, no. 153 = P. Sabino, p. 152). At his death he was "vir illustris cura palatii urbis Romae"; he died aged c. 66 and was buried on 7 November 686: Epitaph, lines 13-15 ("Plato v. ill. cura palatii urbis Romae, vix. an. pl. m. LXVI; dep. m. nob. die VII, indict. XV, imp. dn. Iustiniano Aug. ano II p. c. eius ano II"). His son is alluded to in line 3: "adiecit titulos proles veneranda Iohannes". His earlier career apparently involved much travelling before he attained a high position under the emperor; he then worked in Rome until his death on the restoration of ancient palaces: lines 5-12 ("hic iacet ille Plato, qui multa per agmina lustrans et maris undisoni per freta longa volans claruit insignis regno gratusque minister celebremque sua praestitit esse manu. Post ergo multiplices quas prisca palatia Romae praestiterant curas longo refecta gradu, pergit ad aeterni divina palatia regis sumere cum meritis praemia firma Dei"). His wife, whose epitaph, also by Ioannes 228, was inscribed on the same marble, was "Blatta illustris femina" (see Blatta 1). By the seventh century the title cura palatii (curapalates) usually denoted an important member of the imperial family.
