The beauty of Alexandrine mosaics

The first time I was confronted with the fine and delicate mosaics created in Alexandria was in Libya. 

Unexpectedly, this was in the eastern city of Ptolemais, seeing the centerpieces of the mosaic floors in the Summer Triclinium of the Palazzo delle Colonne. It was as if I could zoom in time and again to discover ever more details! 

Another striking example was exhibited at the local Museum of Sabratha in western Libya. Here it was a carpet-like mosaic depicting the Triumph of Bacchus. The three central roundels executed in fine Alexandrine mosaics stood out against the otherwise rather rough tesserae of the outer mosaic. The top roundel showed Bacchus, after whom the mosaic was named, followed by a lively lion head and a panther head. 

Another example was presented at the Bozar Museum in Brussels during the Exhibition on Alexandria in 2022. Here the fine centerpiece of the mosaic was a wild Medusa face on loan from the Museum of Alexandria dated also from the 2^nd century AD. 

Scenes of gods and goddesses were very common in antiquity, but it seems that animals were generally introduced by the Romans. 

Lesser known is the panel of a colorful parakeet, one of three centerpieces that decorated a floor of Palace V in Pergamon. This is the only one that made it to the Museum of Pergamon; the other two are lost in the mist of time. 

Now the story of this parakeet requires some extra information. To start with, it has been identified as the Psittacula eupatria, noble fatherland or of noble ancestry. Apparently, it was Alexander the Great who sent the first birds from Punjab to the West, where they were received as exotic pets by the rich and famous of his time. 

The mosaic panel was made in Pergamon in the days of Eumenes II or Attalus II to decorate the so-called altar room of Palace V on the city’s acropolis.

The technique also used the opus vermiculatum meant to emphasize the contours of the bird – a parakeet in this case. To that effect, one or more rows of dark tesserae would be inserted around the subject to enhance the pictorial effect and create an extra contrast or a shadow.   

It is hard to imagine how the artisans of those days were still able to see what they were doing handling those tiny bits of stone, marble, and glass varying between 0.5 to 1 millimeter in size and keeping an eye on the contrast effect at the same time. High-skilled craftsmanship, no doubt.
