“All dots interesting–but you say nothing about the polka. Is the rosary a sort of dance?” commented Jack Foley.
There was no reason for “polka” to be linked with “dots” except, according to Wikipedia, that the dance step was very fashionable in the mid 1800’s, and thus, might be a selling point for the new dot-pattern. “Many other products and fashions of the era also adopted the polka name.”
Just as the dots give a whimsical impression, polka’s quick and light steps bring to mind the vibrancy of life. When I see polka dots on anything I swear they dance.
As for the rosary, active counting brings believers closer to their God. Isn’t that also a kind of dance?
