Lucia Wiley (April 14, 1906 – August 20, 1998) was a noted New Deal muralist and painter born and raised in Tillamook, Oregon.

Her thesis was a study of true fresco, a centuries-old technique in which color pigments are added directly to wet plaster.

[2][5][6][7] In the early 1940s, the U.S. Treasury Department held a competition for fresco artists to create murals in post offices around the country.

Wiley won a commission, and a group of citizens requested that her fresco be installed in the new post office being built in Tillamook.

The Treasury Department agreed, and she began the tedious work of preparing the walls and installing the mural, completing it in 1943.

But in 1955, she resigned from the Portland Art Museum to become a postulate at the Episcopalian Community of the Holy Spirit at St. Hilda’s House in New York City.

And I had the Episcopal Church there, and I had a lovely home I had bought, but this wasn't enough...there was something more that I was hungry for, and it just grew about gradually.” [2] Sister Lucia soon became the supervising art teacher at St. Hilda’s, where she also taught math, English, social studies, and religion in the Community’s two schools.

She became Sister Warden of Associates, serving as an adviser to postulates, novitiates, and ordinates of the Community of the Holy Spirit.
