This is the work of Leonidas or Antipater (A.P. 7.316). By including it in Hellenistic Epigrams as Leonidas C, Gow and Page imply that it is likely to be by Leonidas of Tarentum or Antipater of Sidon, not their later homonyms Leonidas of Alexandria and Antipater of Thessalonica.
Τὴν ἐπ᾿ ἐμεῦ στήλην παραμείβεο, μήτε με χαίρειν
εἰπών, μήθ᾿ ὅστις, μὴ τίνος ἐξετάσας·
ἢ μὴ τὴν ἀνύεις τελέσαις ὁδόν· ἢν δὲ παρέλθῃς
σιγῇ, μηδ᾿ οὕτως ἣν ἀνύεις τελέσαις.Pass by this monument, neither wishing me well [= greeting me], nor asking who, or whose son, I was. Otherwise may you never reach the end of the journey you are on, but if you pass by in silence, not even then may you reach your journey’s end.
