I want to know the answer to the following question:
Who identified Ashkenaz with the Saquliba or Slavic territories?
All the background I'm provided with is that "In the Yoma tractate of the Babylonian Talmud the name Gomer is rendered as Germania, which elsewhere in rabbinical literature was identified with Germanikia in northwestern Syria, but later became associated with Germania.". Is that enough to answer the question?
Answer: no
