This seal first appeared in 1765 on the title page of the Reverend Thomas Bacon's compilation of the Laws of Maryland, and until 1793 it ornamented printed editions of the session laws of the Assembly. Carved on a wood block by Thomas Sparrow, ward and employee of the Annapolis printer, Jonas Green, the Sparrow seal bears the Latin motto "Crescite et Multiplicamini," which means "Increase and Multiply."
