Excursus

What was the mysterious location to and from which the four had just been transported?

What was the header, to which they alluded? Was it really a mosaic of Byzantine inspiration?

Who was the alluring Davina Lopez, of the fascinating book review?

What was the significance of the enigmatic ‘p:ost’, and how could its meaning be decoded?

By what means might one ‘cross the seas and come/To the holy city of Byzantium’?

No signposts have been given, but the four had somehow obtained access to this totally fascinating object of their obsessions. Although lacking invitation or means of conveyance thither, those willing to risk all may enter through this portal - if they dare.
