In the Pierpont Morgan Library, this Book of Hours in Latin and French originates from the Loire region in France about 1475 .
On folio 014r a miniature of the Evangelist Matthew on a bench writing on a desk is surrounded by a border with flowers, a snail and some birds. The snail is dextral with a slightly thickened aperture lip (Helix-like) and its tentacles shown.
Folio 061v shows the Annunciation of Mary by two sheperds, with margins decorated with border of floreate ornaments with butterflies, a bird and a snail. The snail is seen in ‘2D squashed mode’, showing a dextral specimen with a slightly ribbed shell.
The Coronation of Virgin Mary is shown on folio 091v in a miniature, with borders of floreate ornamentation with a woman and two snails. In the left border the snail is seen from the top, in the lower border the animal is shown from the left side. Both specimens are dextral.
Folio 127r illustrates in a miniature the Crucification of Christ. The borders are populated with a butterfly, bird, snail, fly and a grotestque. The snail is a dextral specimen, with two tentacles shown.
Pentecost is shown in the miniature on folio 139r, with borders illustrating flowers, butterflies, a snail and a hybrid. The snail has a dextral shell; the head of the animal is drawn with two tentacles and a humanised face, the whole looking like the head of a sheep.
Finally, folio 330r shows in the miniature the Deposition of Christ; the borders are decorated with floreate ornaments, two birds, a snail and a woman riding on a hybrid bird. The snail is seen from the left side with a more or less stylised shell (dextral) and the animal with two tentacles.
All shells are brownish and may have been modeled after a Helix species.
