I want to know the answer to the following question:
What was the first Latin phrase used by the Royal Institute?
All the background I'm provided with is that "The description in the 1837 by-laws was: "gules, two lions rampant guardant or, supporting a column marked with lines chevron, proper, all standing on a base of the same; a garter surrounding the whole with the inscription Institute of British Architects, anno salutis MDCCCXXXIV; above a mural crown proper, and beneath the motto Usui civium decori urbium ".". Is that enough to answer the question?
Answer: yes
