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.
