This person has an 'elbow ornament' which might be showing a completed round (e.g. as a sign for the diurnal cycle of the sun as viewed down on earth in contrast to the fixed star nights of the moon high up in the sky).

Hb3-9 Hb3-10 (110) Hb3-11
Pb5-15 Pb5-16 (172)

... About Carmenta we know from the historian Dionysus Periergetis that she gave orcales to Hercules and lived to the age of 110 years. 110 was a canonical number, the ideal age which every Egyptian wished to reach and the age at which, for example, the patriarch Joseph died. The 110 years were made up of twenty-two Etruscan lustra of five years each; and 110 years composed the 'cycle' taken over from the Etruscans by the Romans.

The day following the Terminalia (February 23) was doubled, forming the 'bis sextum - literally 'double sixth', since February 24 was 'the sixth day before the Kalends of March' using Roman inclusive counting (March 1 was the 'first day').
