Uno dei Trenta — Residential (Amberel Top Cache geocoin)

It struck me that Amberel's elegant design bears a striking resemblance to a classic spiralling labyrinth. Such a structure certainly has relevance to the cache that this coin celebrates, for entry to the seventh circle is guarded by the great Minotaur, who normally resides in the labyrinth of Knossos.

Furthermore, scholars observe a distinction between a maze and a labyrinth. According to Wikipedia:

Maze refers to a complex branching (multicursal) puzzle with choices of path and direction; while a single-path (unicursal) labyrinth has only a single, non-branching path, which leads to the centre. A labyrinth in this sense has an unambiguous route to the centre and back and is not designed to be difficult to navigate.

 I would argue that this also applies to il Nono Cerchio. There are not many alternative paths that may be taken (for more than a few metres anyway), so the navigation is generally "unicursal". That is not to say that the journey is easy, of course.

The ninth circle, however, is ultimately dominated by treacherous characters. This piece of silver now resides there; it should not be removed please, but it is hoped that it is discovered by any who venture to those depths. 

This geocoin was kindly made and awarded by Amberel, for the cache il Nono Cerchio. As with all the Amberel coins that we are fortunate enough to have been given, this is a treasured geocoin, so please leave it in situ for future adventurers to discover.

How to find this coin

From the cache of il Nono Cerchio, head back towards the T-junction where you joined this passage. Instead of turning left, continue north-west, as far as you can go. You should soon discover the coin. It resides in its own bespoke hide. It is hidden in exactly the same way as the cache itself, so please use the same finding techniques. Feel free to discover it, but please replace it exactly as you found it.
