On the Alexandrian tetradrachms of
Aurelian and
Vabalathus, V's combined diadem and
laurel wreath is much clearer, so has long been recognized; already stated as an established fact by
Eckhel VII, 1797, p. 492, "Caput laureatum et diadematum puerile", "Youthful
head laureate and diademed".
Surprising, then, that it took people so long to recognize the diadem on the
antoniniani! In
his description of the
antoniniani on the same page,
Eckhel has merely "Laureate
head". Similarly
Cohen, as I stated, and Rollin &
Feuardent in their very useful and perceptive stock
catalogue of
Roman coins, c. 1880. Even
Bastien by the early 1990s did not know about the combined diadem and
laurel wreath on the
antoniniani!
I will have another look at Estiot's
Aurelian catalogue tomorrow, for it strikes me that she certainly must know, and probably also informs the reader, who was responsible for this little discovery!
