The seven branched candlestick is a reference to the gold Menorah stolen during the Roman raid on the Second Temple in 70 CE. and taken to Rome. Its location has been unknown since the 5th century, with speculation that the Vandals took it during the sack of Rome in 455 CE. There are many rumors about its location, including that it sunk to the bottom of the Tiber after a shipwreck (Povoledo).
