Exegesis:
eikōn (only here in Mark) ‘image,’ ‘likeness.’
epigraphē (15.26) ‘inscription,’ ‘legend (on a coin).’
The silver denarius bore, on the obverse, the likeness of the emperor’s head, in high relief, with the following inscription surrounding: TI CAESAR DIVI AVG F AVGVSTVS (‘Tiberius Caesar Augustus, son of the divine Augustus’).
Translation:
Likeness is translated as ‘picture’ (Southern Subanen, Amganad Ifugao), or ‘written mark’ (Tzeltal). In some languages engraving is referred to as ‘cutting.’ Caesar’s may require expansion to ‘these belong to Caesar.’
