Here's another cool coin. This one is a 1,900 year old Roman silver denarius. It was minted in 97 AD, under the emperor Nerva, near the height of the Roman Empire. This coin was a customary day's wage, worth about $60 in purchasing power. In its time, it was the standard daily pay of an ordinary soldier of the legion or of a skilled laborer or crafts-person.
The reverse side of the coin is the cool part. It shows a set of religious implements used in pagan Roman rituals. From left to right, these are the simpulum, aspergillum, jug, and lituus.
The simpulum was a long handled ladle used to drink or pour out wine or other liquids as an offering. (The practice has largely died out, but think of someone pouring out a 'toast to the gods' in contemporary fiction. This is a cultural derivative of the practice.) Sometimes the wine or oil was poured onto an animal (anointing) that would later be sacrificed (which often amounted to the animal being barbecued and eaten - with some ceremony). Simpler rituals used a cup (grail / chalice) or bowl (patera) for the same purpose.
Next is the aspergillum. The aspergillum was a brush on the end of a stick, used to sprinkle people with perfumed water or some other version of holy water. The horsehair aspergillum and other versions of sprinklers were borrowed forward into Christianity, along with the tradition of sprinkling holy water, almost completely unmodified from classical Roman paganism. Aspergillum are still used in some sects, and some orthodox versions even still use horsehair brushes! Also, this is where we get the word for the vegetable asparagus, because they look like little paint brushes.
Next is a jug. It's not that fancy. It held the oil, wine, milk, or whatever liquid was to be offered.
And finally, on the right, is the lituus. This object also still exists, borrowed forward into Christian symbolism. To see one, Google image search the word 'crosier.' A crosier is a lituus. But the ancient function of the lituus has completely disappeared from modern culture, and a 'crosier' is now just a symbolic religious staff. In ancient Roman times, it was held out by a particular type of pagan priest, an auger, who used it to define an area of the sky in which they observed the direction of the flight of birds. From the details of what happened within this observed space, they provided guidance in military and other major decisions. Auger means 'teller,' or 'one who tells.' We know quite a bit about this ancient divining and fortune telling tradition from two existing early Roman texts, the Commentarii Augurales and the Libri Augurales.
