Here is Prior's portrait of his future wife, Rosamond. He met her when he went from his hometown of Bath, Maine, to Portland to seek training in the painting trade. After arriving in town, he went to the best known house painter in the area, Avery Hamblin. As luck would have it, Avery had a daughter. Here she is. Prior painted her in 1824 and married her in 1828.
The inscription reads: "W. M. Prior, Painter, formerly of Bath, 1824, 3 piece on cloth, painted in C. Codman's shop, Portland, Maine." Codman was a marine painter that Prior trained with in his early years.
In making such a detailed inscription Prior was documenting himself in preparation for an artistic career. What we may never know is what personal thoughts he may have had in mind while painting Rosamond. He may have been showing off a bit for her by adding so much detail. It does seem that he made the right first stop when arriving in Portland, and certainly had a flair for impressing his patrons.
