The Secundinus stone, with its combination of carved phallus and text, was found in 2022 in excavations within the stone fort at Vindolanda. We consider comparanda for the imagery from Vindolanda, Britannia and further afield, and textual parallels particularly from Pompeii. We offer several possible interpretations of the object and prefer an analysis which takes the text, SECVNDINVS CACOR, as it is carved. This interpretation would add an otherwise unattested verbal form to the Latin scato-sexual vocabulary.
