Candidate passages:
The mosaic, with an arch-headed framing that identifies its original location as flooring an apse in a grotto, features detailed depictions of Ptolemaic Greeks, black Ethiopians in hunting scenes, and various animals of the Nile river.
It is the earliest Roman depiction of Nilotic scenes, of which several more were uncovered at Pompeii.
A consensus on the dating of the work is slowly emerging.
Paul G. P. Meyboom suggests a date shortly before the reign of Sulla (ca.
100 BC) and treats the mosaic as an early evidence for the spread of Egyptian cults in Italy, where Isis was syncretised with Fortuna.
He believes Nilotic scenes were introduced in Rome by Demetrius the Topographer, a Greek artist from Ptolemaic Egypt active ca.
165 BC.
Claire Préaux emphasises the "escapist" nature of the fantastic scenery. 
Billingsgate Fish Market, in east London, is the United Kingdom's largest inland fish market.
It takes its name from Billingsgate, a ward in the south-east corner of the City of London, where the riverside market was originally established.
In its original location in the 19th century, Billingsgate was the largest fish market in the world. 
Cleopatra VI Tryphaena () was an Egyptian Ptolemaic queen.
She may be identical with Cleopatra V. There were at least two, perhaps three Ptolemaic women called "Cleopatra Tryphaena": 
The Ptolemaic Baris (also Ptolemaic Acra) was a citadel maintained by Ptolemaic Egypt during its rule of Jerusalem in the 3rd century BC.
Described by only a few ancient sources, no archaeological remains of the citadel have been found and much about it remains a matter of conjecture. 
The most detailed account of the Ptolemaic citadel is to be found in the Letter of Aristeas, an account of the translation into Greek of the Septuagint.
In one section, the author, supposedly an Alexandrian Jew in the service of Ptolemy II Philadelphus (309 BC – 246 BC), visits the Temple Mount and is then invited to visit the Baris as well:The exact location of the citadel is not specified in this account, but the mention of an ascent to the Baris, as well as its location in a "very lofty spot", suggests the citadel overlooked the temple enclosure.
As the citadel is in close proximity to the Temple, not on one of the other hills surrounding Jerusalem, the topographical nature of the Temple Mount affords only one such location – a rocky outcrop north of the temple enclosure, a spot where Herod the Great later built the Antonia Fortress.
This is the precise location where the Persian citadel is supposed to have stood, suggesting the two may indeed be identical.
It is not entirely clear when the Letter of Aristeas was written, although it is certainly much younger than the time of its supposed creation, in the middle of the 3rd century BC.
Opinions differ on the exact date, although current research suggests the middle of the 2nd century BC.
Such a date would rule out the Hasmonean Baris or Antonia Fortress as the inspiration for the account, though not the Seleucid Acra.
Thus, although it is not certain, the Letter of Aristeas may indeed preserve a genuine account of the citadel which stood in Jerusalem during Ptolemaic rule.
