Here is an interesting letter from H. Guedalia to the Jewish Standard (December 7, 1888) concerning the hymn Bar Yochai. He asks whether anyone knows if it was ever translated into another language. So after five generations I answer H. Guedalia's question and I say, yes, it was. Oluf Gerhard Tychsen translated it to Latin in 1763, an "Elegia elegans e terra Israel" in honor of "R. Schimenois Filii Iochai,"and he should see my post (link).
He also has some interesting comments about how he supports memorial celebrations like Lag B'omer.
