The crown of mountains that surrounds Palermo and resembles the shape of a necklace was already found, in ancient times, in the
Greek - Phoenician language
of the city’s ancient inhabitants, although the Greek and then Latin origins of the name, Panormos/Panormus, also include the meaning of a port with a deep anchorage, although this was not specifically attributable as it was also used for other sites.
As early as the 12th century, the flourishing vegetation of this vast plain’s landscape, coloured by the pink hues of the lemon plants , the bright tones of the oranges and pomegranates, similar to the blazing streaks of timeless sunsets, was described in detail by Ugo Falcando .
The combination of the term “ conca ” with the fertile plain, as well as a Baroque definition by the Jesuit Giuseppe Mazara , could refer to its iconographic representation in modern times in the shell in the Genius of Palermo sculpture group in Palazzo Pretorio.Going back in time, even the Arabic term dāra can be traced back to the ring of mountains that rises around the lush plain of Palermo, as if to protect it. Even from the adjectives in the local erudite locution “Panormus, Urbsfelix, Concha aurea”, the city seems to express both a link to the flourishing natural resources that surrounded it and a reference to the presumed gold sands of the Oreto river, whose very etymology derives from the presence of gold. The colour of this noble metal, associated with the royal purple-red, echoes the heraldic tradition already present in the Roman-Byzantine era and the colour scheme of the city of Palermo in the Islamic Middle Ages.
