1. English (Late 11th century). This hat is most likely either a felt cone, or an assembled cap.
  2. English (1180-1190). The tab at the peak is quite common. Note that this same design is also appropriate for a 4th century Jew.
  3. Anglo-Saxon Cap
  4. Anglo-Saxon Scythian Cap
  5. Anglo-Saxon (c9th - 11th century)
  6. English (1180-1190)
  7. English (c1260)
  8. This *looks* like a simple knitted cap, although it could be intended to represent a crushed felt cone.
  9. Anglo-Saxon Scythian Cap
  10. Anglo-Saxon Cap
  11. Anglo-Saxon - an early version of the coif?
  12. A stylized "Scythian Cap" sometimes seen in Illustrations.
  13. This style of hat is most often worn as part of the legislated clothing intended to single out the European Jews (12th century)
  14. As above, this is also a "Jew's Hat". This design is sometimes seen in straw?
  15. Worn both with a chin string, and without, this basic design is seen over again, from a Cardinal's "Red Hat" (14th Century) worn with cords, beads and tassels, to a straw hat (1350-1420), and an Italian Felt Hat (c1470)
  16. Resembling a "top hat", this is, in fact, a Beaver hat. Before the 16th Century, the Beaver fur was not felted, but rather left on the skin, and the hat made of the leather.
  17. This basic style is seen in felt, straw and in later era knitted caps.
  18. Another possible rendition of the previous style.
