Ancient Artefact of the Day: A bronze statuette of a griffin battling with a human figure, perhaps intended to be an Arimaspian, ca. 125-75 BC. #AAOTD #Griffin

Image: J. Paul Getty Museum (96.AB.152)
The provenance of this piece is not clear, although its small size (7.9 cm high) is suggestive that it may originally have been a an attachment to a large bronze vessel.
Certainly as early as the seventh century BC, griffin heads were used as decorative elements on cauldrons. This example is particularly fine, found in the bed of the Kladeos river at Olympia in 1914, associated with the sanctuary of Zeus.

Ancient Coin of the Day: an Aureus of Hadrian, ca. AD 134-138, with a design of Romulus on the Reverse with the Legend "ROMVLO CONDITORI", suggesting Hadrian's presentation of himself as a second founder of Rome. #ACOTD #Hadrian

Image: RIC II Hadrian 370
In the latter years of his reign, Hadrian issued several coins and medallions that made a connection between himself and the founder of Rome. Also noteworthy here is the rejuvenated portrait of Hadrian, without the beard.
The simple Legend on the Obverse, "HADRIANVS AVGVSTVS P P" - 'Hadrian Augustus, Father of the Fatherland', also speaks towards a streamlining of message, perhaps to further connect him with the founder of the city.

No.3: When you're sure that someone DID mention Ovid...
