The Historical Gap between Linear B and the earliest use of the Greek alphabet:

Once Linear B fell out of use around 1200 B.C., written Greek disappeared entirely for approximately
400-500 years, only to re-emerge in an entirely new script, which of course we know as the Greek
alphabet (and variants thereof).  What happened between ca. 1200 BC and ca 800-700 BC no-one
really knows.  On the other hand, the earliest Greek authors, including Homer and Hesiod, make
reference to to previous writers who in fact did make use of some form of the primitive Greek
alphabet as such.  The difficulty lies in the fact that none of these earlier literary works (almost
certainly poetry) survive, so that there is no way for us to know when the Greek alphabet, in its most
primitive form, first manifested itself. While the period elapsed (in centuries) between the time Linear
B fell into disuse (around 1200 BC) and the time literature first emerged in the Greek alphabet
(however primitive) is a complete unknown, it is possible to infer that the earliest literature written in
the Greek alphabet probably preceded the composition of the Iliad and the Odyssey.  The difficulty lies
in the fact we cannot know how long that gap was.  Was it as little as two centuries or as long as four?
No one knows, nor will we likely ever know. However, it is my belief that the first use of a primitive
form of the Greek alphabet did in fact precede Homer. I only wish we knew when. I say this simply
because, if the lapse between the loss of Linear B inscriptions and the first use of the primitive Greek
alphabet was in the order of only two centuries, give or take, then it is possible that the earliest writers
using the Greek alphabet may have been aware of the prior existence of Linear B, though this is
doubtful. I will, however, have more to say on this matter later.
