Tab.Vindol. III, 628 is a letter of an auxiliary decurion of cohors VIIII Batavorum that begins with the greeting ‘Masclus Ceriali regi suo’. A.R. Birley tentatively suggested that the title held a literal force, while Bowman and Thomas interpreted the word as meaning ‘patron’ on the basis of OLD s.v. 8 and a parallel with P. Mich. 8.472 = CEL 147, a letter, also from a military context, from ‘Claudius Tiberianus Longino Prisco domin[o] et regi suo’. This article examines the Batavian and military contexts of these interpretations alongside other epigraphic examples of rex as ‘patron’.
