No luck

Anyone know where phrase "leaps and bounds" originated?

I couldn't find it.

by leaps and bounds Rapidly, or in fast progress, as in "The corn is growing by leaps and bounds," or "School enrollment is increasing by leaps and bounds." This term is a redundancy, since "leap" and "bound" both mean spring or jump, but the two words have been paired since Shakespeare's time and are still so used.
