A travelling speculator (CIL III 1650) a glimpse of the everyday life of the principales through the window of Roman funerary art

The focus of the paper is on the travel scene depicted on the funerary stele of L. Blassius Nigellio (CIL III 1650), a speculator of legio VII Claudia, from Viminacium.
