Fielding Lucas Jr. (September 3, 1781 – March 12, 1854) was an American cartographer, an artist, and a publisher of prominence during the early 19th century.

In the 1845 issue, he inserted a map of the United States, "prepared at much expense to exhibit at a glance the extent and relative situation of the different dioceses", with a table of comparative statistics from 1835 to 1845.

Because of Lucas and a younger contemporary, the Ireland-born John Murphy, Baltimore was the major center of Catholic publishing until it moved to New York City at the beginning of the twentieth century.

Colored illustrations of flowers were accompanied by a text which guided the reader through the hidden meanings of different blooms, with quotations and poetry appropriate to each.

Similar works were issued at every level of quality and size, from pocket-sized volumes with crude plates to highly finished folios.
