Is Rabbi Solomon Jarchi the same as Rashi? I saw Jarchi on the Internet on a Google search awhile ago, that it was Salomo son of Isaac, a French Biblical commentator and was wondering if it was the same thing as Rashi.
To quote S. from On The Main Line:
Rashi was known by Christians as Rabbi Solomon Jarchi (Yarchi) because of a mistake, the mistake being that it was thought that 1) he was from Lunel and 2) that the yud stood for ירחי, which was Hebrew for "from Lunel" (Lunel as in luna as in moon).
This mistake was so entrenched that the Chida (page 6 in linked PDF) seriously considers it in his Shem Hagedolim in his entry on Rashi. As I have noted elsewhere, by the 18th century Christian scholars were already noting that it is a mistake, and by the mid 1800s it almost became common knowledge.
Yes, they are the same, according to this article. It was apparently his last name (maybe what he went by in legal papers).
