St. John at the Last Supper in an initial S

Zurich, 1260-80
Ink on parchment
MS. MsWettF 2, folio 176r
Aargauer Kantonsbibliothek, Aarau, Switzerland

Above the illustration is the rubric, Explicit epistola sancti iohannis secunda. Incipit eiusdem tercia. – "St. John's second letter ends. His third begins." The "S" of Senior (the first Latin word of 3 John:1) is formed by the snake-like creature with the bird-like head behind Jesus and John.

As in many other Last Suppers, the meal before them is a fish rather than a lamb. The items to the left of the fish appear to be two hosts (one broken) and a chalice.
