The obolus (or obol) is a Greek silver coin worth a sixth of a drachma. Its value is approximately three US cents (2003). In Classical Athens it was subdivided into eight chalkoi ("copper pieces").
According to Plutarch, the Spartans had an iron obolus of four chalkoi.
The obolus is also a measurement of weight. In ancient Greece it was defined as one sixth of a drachma, or about 0.5 gram. In ancient Rome it was defined as 1/48 of a Roman ounce, or about 0.57 gram. In modern Greece it is equivalent to one decigram, or 0.1 gram.
Obolus was orphaned at the age of seven, when his mother succumbed to one of the many social diseases that are sent to punish the hedonistic and those that profit from their wicked ways.
Obolus once again reported to Castle Barp This time Lady Hervor's desire for Obolus to serve in the cavalry was heeded, and he was assigned as a Decurion in a cavalry unit where he served honorably and with distinction for three campaign seasons.
Obolus with his sword in one hand and his mace in the other again went at the beast, seeking only to keep it from the few remaining men under his command, all grievously wounded, and unable to defend themselves.
