This Wednesday’s watermark comes once again from the Islamic Manuscripts Collection - one of the papers in Isl. Ms. 463 v.2 to be exact. It features an anchor watermark set in a circle with a six-pointed star above.
The anchor is another motif extremely popular among Italian papermakers of the 16th and 17th centuries, and it appears quite extensively in manuscripts produced in the former Ottoman lands during this period.
The anchor could be drawn in one line or two and could be accompanied by various motifs - ring, star, flower (or leaf), initials, etc. Among Italian makers, the mark was typically set in a circle and often paired with a countermark featuring the intials of the papermaker.
Vladimir Mošin has filled an entire volume with various types of anchor watermarks for which he established a typology for classification. The mark in Isl. Ms. 463 v.2 corresponds to Mošin's Type It. IV 2.f (a), an Italian mark of an anchor drawn in a single line, encircled, with a six-pointed star above and no countermark.  Several other marks of this type are contemporary with the mark in the paper of our manuscript, which dates to roughly1579 or 80.
All in all, at least 67 volumes from the Islamic Manuscripts Collection include at least one type of "anchor in circle" watermarked paper, all dating from the mid to late 16th to the early 17th century.
Anchors far and away!
