Tosefta Shabbat 17:1
ToseftaAn inscription which runs under pictures or busts [of rulers] - they do not look at it on the Sabbath. Not only so, but also on an ordinary day they do not look at the busts, since it is said, 'Do not turn to idols or make for yourselves molten gods' (Lev. 19:4). A. R. Eleazar b. R. Yose the Galilean says, 'If you see a righteous man go on a journey and you plan to go on that same journey, push up your trip for three days or postpone it for three days on his account, so that you may go on the journey with him. On what account? 'Because angels of peace accompany him'.

"... On the practice of placing inscriptions at the base of a statue see Henderson, Pliny’s Statue, 33-36. Inscriptions often contained dedications invoking the gods or honoring a person. Scholars from Loewe to Finney have noted the connection between Jesus and the coin (Mark 12:13-17; Matthew 22:15-22; Luke 20:20-26) and Jerusalem Avodah Zarah 31:1, 42b; however, they have not noted the much closer temporal and terminological connections with Tosefta Shabbat 17:1 (eikon, legend, closer in time) ..."
