Antioch, the great metropolis in Syria, was similarly positioned, as it was about the same distance (c. 15 miles) from its Mediterranean port at Seleucia. Though essential to major inland cities, ports and harbours were perhaps the most challenging of all engineering projects, and they were very costly to build and to maintain. It comes as no surprise that when great ports were completed, it was cause for celebration. To Romans, such occasions not only affirmed their international renown as engineers, but also represented a new opportunity to reap benefits in transportation, trade, grain supplies and military applications. The construction of a port at Ostia had been considered by both Julius Caesar and Augustus, but the projected expenses were so daunting that it was not until Claudius came to power that construction began; finally, it was finished during the reign of his adoptive son Nero.

Ex Tinchant Ostia was the port of Rome and mentioned as being Rome’s first colony in the 7th century BC. It was an important port in Republican times and also under Julius Caesar. During the reign of Claudius an artificial port, which can be seen on this coin, was built and inaugurated under the reign of Nero in 54 AD. It was further developed under Trajan. During the latter part of the empire, the harbour silted and the surrounding land was stricken by malaria epidemics, so that in 800 AD the last remaining inhabitants were relocated.

As an inland city of more than one million people during the reign of Nero, Rome relied heavily upon its Tyrrhenian Sea port at Ostia. Antioch, the great metropolis in Syria, was similarly positioned, as it was about the same distance (c. 15 miles) from its Mediterranean port at Seleucia. Though essential to major inland cities, ports and harbors were perhaps the most challenging of all engineering projects, and they were very costly to build and to maintain. It comes as no surprise that when great ports were completed, it was cause for celebration. To Romans, such occasions not only affirmed their international renown as engineers, but also represented a new opportunity to reap benefits in transportation, trade, grain supplies and military applications. The construction of a port at Ostia had been considered by both Julius Caesar and Augustus, but the projected expenses were so daunting that it was not until Claudius came to power that construction began; finally, it was finished during the reign of his adoptive son Nero. There are several variants of this famous reverse type, all of which show the harbor from a bird’s eye view, but which vary in the type and positioning of the vessels, which number from seven to twelve. Some fixed features are the breakwater and warehouses that form the perimeter, the Imperial statue at the top, the ocean-god Neptune holding a rudder and reclining on a dolphin at the bottom, and the inscription AVGVSTI POR OST SC. As successful as the harbor proved to be, it was not infallible. Tacitus reports that in 62 a storm sank 200 vessels that were anchored within the harbor, and by the reign of Trajan the harbor had to be greatly expanded. The depiction on this particular coin shows eight vessels, ranging from large commercial ships to a small transport vessel.

While Julius Caesar recognized the value of expanding Rome's port facilities at Ostia, it was Claudius who began actual building in AD 42. As part of the construction, one of Caligula's pleasure galleys was scuttled and filled with cement; above it was constructed a lighthouse surmounted by a statue of Neptune. Although the actual date of completion is not certain, it must have occurred shortly before this sestertius was minted. A further expansion of the facilities was required under Trajan and Hadrian. By the fourth century, however, the port's importance began to diminish as a result of silting. Soon the region became a breeding ground for malaria and was abandoned.

Veniamo alle conclusioni. Al di là della questione del peso fuori norma che potrebbe essere la conseguenza di un banale errore di misura o di trascrizione, lo stile è talmente improbabile da non lasciare dubbi sul fatto che la moneta sia una riproduzione moderna di pessima qualità. Anche le leggende sono realizzate in modo molto approssimativo. Devo ricordare che la tipologia numismatica in esame è stata oggetto di imitazione sin dai tempi del famoso incisore rinascimentale, Cavino morto nel 1570 (si veda nel link l'immagine di un riconio di Cavino). Esistono dunque della moneta infiniti tentativi di riproduzione e di ri-riproduzione di cui in allegato ho riportato diversi esempi. Tra le varie riproduzioni, la più affine al campione in esame è quella di cui al link n°10 dell'allegato, della quale per altro non possiede i dettagli e i pregi figurativi. Altro non saprei dirle.

Un saluto cordiale.

Note:
(1) Sesterzio (oricalco). Riferisce  il RIC I (pag. 156) che il sesterzio di Nerone aveva un peso prevalente di 26÷30g. Raccolgo in tabella le caratteristiche fisiche dei sesterzi della tipologia di figura reperiti nel web:

Rif. Peso (g.)  Asse di conio (ore) Diametro (mm)
Link1 21 - -
Link2 27,15 - -
Link3 27,85 - -
Link4 24,76 - -

Link10 27,69 6 -
Link11 27,44 - -
Link12 28,76 6 36
Link13 29 6 -
Da quanto sopra espresso si evince che, per quanto concerne il peso, il sesterzio di figura presenta caratteristiche (43,60g, 36mm, 6h) assolutamente anomale. La moneta originale era di oricalco, cioè di una lega contenente circa il 75% di rame e il 25% di zinco, più tracce varie (stagno, piombo, ecc.), priva pertanto di ferro. Il lettore non ha fornito elementi circa l'eventuale presenza di ferro nel tondello, del resto facilmente accertabile per mezzo di un magnete.
(2) NERO CLAVDIVS CAESAR AVGustus GERmanicus Pontifex Maximus TRibunicia Potestate IMPerator Pater Patriae. La moneta fa parte di una serie in oricalco che viene attribuita all'incirca al 64, caratterizzata da IMP posto come cognomen, cioè quasi alla fine della leggenda, e dalla sigla SC nel rovescio. Per il profilo biografico di Nerone rimando alla pagina omonima del portale dell'Enciclopedia Treccani (v. link).
(3) La leggenda del rovescio va letta unendo la parte superiore, "AVGVSTI", a quella inferiore privata delle lettere d'inizio e fine che esprimono la sigla senatoria SC e dunque AVGVSTI PORTus OSTiensis (Porto Ostiense di Augusto). Traggo la descrizione e i commenti sul tipo del rovescio dalla moneta n° 12: "in alto, faro sormontato da statua di Nettuno con scettro; sotto, personificazione del Tevere disteso che sorregge un timone e un delfino; a sinistra, molo a forma di mezzaluna, con portico terminante con personaggio sacrificante su un altare e con edificio; a destra, frangiflutti o scivoli a forma di mezzaluna". Alla fonda alcune navi (più spesso in numero di sette, talora di otto o più). Claudio dette inizio ai lavori nel 42 d. C.. Come parte della costruzione, fu riempita di cemento e affondata una delle galere di Caligola e su di essa eretto un faro sormontato dalla statua di Nettuno. Anche se la data effettiva della fine dei lavori non è certa, si suppone che l'opera sia stata completata poco prima della coniazione del sesterzio. Un ulteriore ampliamento delle strutture portuali si rese necessario sotto Traiano e Adriano. Nel IV secolo, l'importanza del porto iniziò a diminuire a causa dell'insabbiamento. Ben presto la zona divenne malarica e fu abbandonata. Nel link che segue l'ipotesi ricostruttiva del porto (v. link) e l'immagine di come si presenta oggi, dopo la bonifica moderna, la parte più interna del porto realizzata sotto Traiano agli inizi del secondo secolo (v. link).
