The Great Sothic Cycle was a calendrical cycle based on the heliacal rising in July of the star Sirius (known to the Greeks as Sothis) and lasting approximately 1460 years. According to ancient Egyptian mythology, in a Golden Age, the beginning of the flooding of the Nile coincided exactly with the rising of Sirius, which was reckoned as the New Year. Only once every 1460 years did Sirius rise at exactly the same time. Thus, the coincidence of this along with the concurrent beginning of the flooding of the Nile gave the event major cosmological significance by heralding not just the beginning of a new year, but the beginning of a new eon. This event also was thought to herald the appearance of the phoenix, a mythological bird which was reborn every 500 to 1000 years out of its own ashes. According to one version of the myth, each new phoenix embalmed its old ashes in an egg of myrrh which it then deposited in the Egyptian city of Heliopolis. So important was the advent of the new Great Sothic Cycle, both to the realignment of the heavens and its signaling of the annual flooding of the Nile, that the Egyptians celebrated it in a five-day festival which emphasized the important cosmological significance.

In the third year of the reign of Antoninus Pius (AD 139/40), a new Great Sothic Cycle began. To mark this event, the mint of Alexandria struck an extensive series of coinage, especially in large bronze drachms, each related in some astrological way to the reordering of the heavens during the advent of the new Great Sothic Cycle. By the time that these coins were issued, the Egyptian names for the various constellations had been replaced by those more familiar to the Greeks and Romans. Among the issues struck during this time was this very rare type depicting a plowsman and may refer to the constellation Boötes, the mythological figure who invented the plow. Since the appearance of Sirius heralded the beginning of the Nile’s flooding, which deposited a rich alluvial layer of mud on the fields, necessary for the growing of grain, the inclusion of the constellation associated with the originator of the plow would have made perfect sense, given the agricultural significance of the Great Sothic Cycle and the importance of Egypt in providing grain to the rest of the empire.
