If artist Hieromymous Bosch designed antique French buttons, I imagine they’d look like worms with heads & snakes. My reference book says these are Seps, snake-like mythological creatures with the heads of other animals. What do you see? I see a rabbit, dog & cat heads.
Grapes were a popular theme among Victorian buttons. Grapes often represented Christ the with fruit & leaves symbolizing the Christian faith. Grapes themselves represented the sacrificial blood of Christ. The leaves stood for rebirth. The vines a representation of bounty.
Grapes are one of the earliest cultivated crops & the fruit & their vines are sacred to Bacchus, the Roman god of wine. As such, these vines take on a jovial symbolism, representing celebration & abundance.
These are just a few examples of antique buttons with a grape motif.
A Bacchante or Maenad, female followers Bacchus, the god of wine.
Carved mother-of-pearl over abalone.
Black glass with silver & blue luster.
Cattail design with interior twinkle rim.
These storybook buttons feature a character "Mr. Rook." The design was a based on a story, "The Ballad or Mr. Rook," written by George Wyndham, chief secretary of Ireland, & illustrated by his wife Madeline, to entertain their ill son.
The story was published in 1901 in verse form, about a company of rooks (birds smaller than crows) who gather in Clouds, Mr Wyndham's family neighborhood. There the birds find a safe place to nest & a kind lady to feed them. The bird with the umbrella is based on an illustration from the story, because even delicate Victorian birds need not get wet.
Perhaps it was the influence of heraldry images on livery in the UK. Or it may have been the Arthurian revival in fiction & non-fiction stories of the 19th century that made armor & weaponry a popular subject for Victorian buttons. The last button above depicts Jean La Hache, aka Jeanne Hachette, a French heroine who helped to defend the town of Beauvais in 1472. She took an ax to an invading soldier who had scaled the city walls & was joined in battle by other women to defend their town. In this scene she is poised to attack one man while another falls to his death. The city celebrates with a holiday in her honor every June.
