If we were to examine Thrace topostrategically, we can equate it to the notion of the angle, when its center, as a peak, is of course Constantinople. In the same context, if we examine the southern part of the Balkans, we will detect another angle, which is consisting of the Peloponnese.
The combination of the two, through mainland Greece, creates topostrategically a biangle. The awareness of this entity has its implications at the strategic level.
If we study the fall of Constantinople in 1453 through the capture of Adrianople and Didimoteicho, then we comprehend that, it occurred from the inner and not the outer corner.
If we now see the liberation of the Peloponnese in 1821, but also the previous one which began in 1669, then, we observe that it occurred with the outer corner.
The coverage of the biangle, forms a chronostrategic context, which created a field of heroism, which was to play a two way battle against barbarism.
The biangle has the protection of the sea, and as a historical background, it unites data, which are seemingly independent, but ontologically connected, through teleology which is associated with the Mediterranean via Crete.
With this composition the battlefield radically evolves into a superstructure of Time.
