Sign Up

Signatures, those seemingly simple scrawls that mark our identity on documents, can reveal a surprising amount about our personalities. While some people opt for a straightforward, legible signature, others embrace the opportunity to express themselves through unique autographs.
The Gemara (Bava Basra 161b) cites a list of Amoraim that used pictures as signatures. Rav used to draw a fish as his signature mark, rather than signing his name. Rabbi Chanina used to draw a palm branch as his signature mark; Rav Chisda used to sign just the Hebrew letter samech. Rav Hoshaya used to sign just the letter ayin. Lastly, Rava bar Rav Huna used to sign his name by drawing a ship’s mast.
Explanations abound as to why each Amora chose his mark. The Rashbam suggests that Rav was accustomed to eating fish, so he chose a fish symbol. However, there are much deeper suggestions offered.
Rav Meir Shapiro established two yeshivas in Sanok, southeastern Poland. One yeshiva focused on Torah studies in the morning and trade classes in the evening. The other offered full-day Torah instruction. He spoke at the grand opening ceremony of one of those yeshivos on Lag B’Omer 1922. He began by noting that Rav chose a fish symbol as his signature. He asked those in attendance what the significance of a fish was. He answered by quoting the Gemara in Berachos (61b).
