Codex vs. Scroll

Below is a comparison of Codex L (11th cent; world's oldest complete Heb. OT, in codex) with Bologna Sefer Torah (12th cent.; world's oldest Torah scroll).  The BST was rediscovered and identified by Mauro Perani last year in Italy.  As visible: Image 1, Codex L (Deut. 16:15c-16:18a); Image 2, Bologna Sefer Torah (Deut. 16:15b-16:18b).  The first word of the BST image below begins with  יְבָרֶכְךָ֞  , the first word after athnach of v. 15 (visible in L), and ends with  לִשְׁבָטֶ֑יךָ , the last word before athnach (visible in L) in v. 18. The nun in the margin is indicating a variation in the sedarim. Image 3 is of BHS Deut. 16 for reference.

Codex L; 11th cent; world's oldest complete Heb. OT. Deut. 16:15c-16:18a; ס marks the sedarim, but is also abbreviation for 2nd word of "פרשה סתומה" or "parashah setumah" = "closed section," when in the text

Bologna Sefer Torah: 12th cent.; world's oldest Torah scroll. Deut. 16:15b-16:18b. 1st word begins with first word after athnach of v. 15; ends with last word before athnach in v. 18. The nun in the margin is indicating a variation in the sedarim. Notice the following paragraph begins on the same line as opposed to a new line as in Codex L above.  (Source of BST image, Mauro Perani.)

The below is a pic. of the same text from BHS, but expanded due to size of photograph.  Notice BHS follows Codex L, as would be expected. 

BHS Deut. 16.

For French readers, here is an article on the BST use of nun in the masoarh parva as seen here, recommended by Mauro Parani, the "rediscoverer" of the Bologna Sefer Torah.   http://www.hum.huji.ac.il/upload/_FILE_1371727598.pdf
