The
attribution 849 is ok. 1490A has an invocative
monogram on the
obv. It does have the dative
legend and the + flanked by decorations as well. That affirms the
attribution to the same individual, but this is not 100% certainty. The
attribution to the brother of
Tiberius III is possible, but also not certain. I'd say it is likely, considering it dates to
his era and that there are not a lot of individuals bearing this name. There is, however, a seal
type that certainly belongs to this famous Herakleios, because it bears
his command of monostrategos, in addition to
his dignity of patrikios (Z/V 1982, online in the DO database). It has an invocational
monogram with Herakleio in the quadrants on the
obv. and
legend on
