How do you express your utter dislike of someone whose name you’re compelled to write? Syriac scribes sometimes recorded the names of unsavory creatures by writing them upside down. I first saw this with the name “Satan” in the Lyon manuscript facsimile of Jacob of Edessa’s Hexaemeron published by Chabot (see f. 15a). I found another example just today in a Garšūnī version of The Story of St. Marina and her Father Eugenius. See here, again the word “Satan” (al-šayṭān), at the end of the second line:
This phenomenon has been noted before for Syriac (see below), but, as far as I know, not yet for Garšūnī. It is, of course, not surprising that a known phenomenon of Syriac scribal habits should appear also in Garšūnī. Other examples in Garšūnī include, from a commentary on the Creed, the name “Apollinaris” written upside down (Dayr Al-Za‘faran 6, f. 59v, col. b), and the name “Nestorius” written upside down in a collection of canons (Dayr Al-Za‘faran 73, p. 418).
Relevant references for Syriac known to me are the following:
- Eugène Boré highlighted the practice, also with the word “Satan”, for a manuscript of Barhebraeus’ Candelabrum Sanctuarii.
- Moberg, in the introduction to his edition of the Book of Himyarites, remarks that the name of “the tyrant Jewish king” Masruq is almost always written upside down in the ms.
- the writing of “Barsawma” upside down in Syriac Orthodox manuscripts has been noted.
- J.F. Coakley, notes an exampled of “Satan” thus written in a printed book from Lebanon in 1902.
- Most recently, Michael Penn has noted a manuscript with the names “Bardaisan” and “Marcion” written inverted.
