[1] In some sources he is called "Jose ben Jose the orphan", on the assumption that only an orphan would receive the same name as his father; however, this assumption is not accurate in relation to all communities at the time.
Alternatively, "orphan" was a title of honor, given due to his being "alone" in his skills and accomplishments.
His poems have been compared to those of Yannai and Kalir, but do not have rhyme schemes and do not allude to midrash, though they do have standard meter.
Most of his poetry has been lost, but some is preserved in the contemporary Ashkenazic prayer books.
Although he was from an era before poets would sign their piyyutim, the Teqiatoth (piyyutim of the special blessings of Mussaf on Rosh Hashanah) of the second day Rosh Hashanah, as well as some of the Selichot of the night of Yom Kippur are attributed to him in early Ashkenazic manuscripts.
