Rashi also influenced non-Jewish circles. His commentaries on the Bible circulated in many different communities especially his commentaries on the Pentateuch. In the 12th-17th centuries, Rashi's influence spread from French and German provinces to Spain and the east. He had a tremendous influence on Christian scholars. The French monk Nicolas de Lyre of Manjacoria, who was known as the "ape of Rashi",was dependent on Rashi when writing the 'Postillae Perpetuate' on the Bible. He believed that Rashi's commentaries were the "official repository of Rabbinical tradition".and significant to understanding the Bible. De Lyre also had great influence on Martin Luther. Rashi's commentaries became significant to humanists at this time who studied grammar and exegesis. Christian Hebraists studied Rashi's commentaries as important interpretations "authorized by the Synagogue".
