Such theories are also connected with the idea that the Mycenaean language constituted a type of a special koine representing the official language of the palace records and the ruling aristocracy. When the 'Mycenaean linguistic koine' fell into disuse after the fall of the palaces because the script was no longer used, the underlying dialects would have continued to develop in their own ways. That view was formulated by Antonin Bartonek. Other linguists like Leonard Robert Palmer (1980), and :de:Yves Duhoux (1985) also support this view of the 'Mycenaean linguistic koine'. (The term 'Mycenaean koine' is also used by archaeologists to refer to the material culture of the region.) However, since the Linear B script does not indicate several possible dialectical features, such as the presence or absence of word-initial aspiration and the length of vowels, it is unsafe to extrapolate that Linear B texts were read as consistently as they were written.
