The hoard of the Roman villa of Boca do Rio (Vila do Bispo, Algarve, Portugal): 90 years after its discovery

The hoard of Roman villa of Boca do Rio (Vila do Bispo, Algarve, Portugal) is a monetary group from the 4th century found inside an amphora in the 30's of the 20th century. In the beginning this hoard had more than 1,000 coins, however only 284 pieces are known today, which have been partially studied by some researchers, From a current perspective, I have compiled all the information on the circumstances of the discovery of this hoard, with the intention of providing more precise information on why it was concealment. I have also proposed a detailed study of the 284 pieces in order to better characterize this hoard; and I have compared the Boca do Rio hoard with other contemporary and similar hoards documented in lusitanian villas, with the intention of contributing a new reflection on the role of the currency in the Late-antiquity rural economies of Lusitania.
