Book IV, Epigram 16 (Ker)

Stepson to your stepmother, Gallus, rumour had it you never were while she was your father's wife. But this could not be proved while your progenitor lived. Now your father lives nowhere, Gallus, your stepmother lives with you. Though great Tully were recalled from the nether shades, and Regulus himself were to defend you, you cannot be acquitted; for she who has not ceased to be such after your father's death, never, Gallus, was a stepmother.
