Linguist Krzysztof Tomasz Witczak argues that Albanians' influence in ancient Greek since at least 7th Century BC is evident in Hesychius and the ancient Spartan poet Alcmans' work:

"The basic conclusion is that the Proto-Albanian lexical influence on Doric Greek started as early as in the 7th century BC. lt is finally suggested that Ancient Greek borrowings from the Proto-Albanian language appeared initially in Alcman's works, which contained a component of the Laconian folk vocabulary of Proto-Albanian origin."
