Insignia
Motto
The phrase Benigno Numine was the motto of the Earl of Chatham. It is generally translated as "With the Benevolent Deity"[3] or "By the Favour of the Heavens".[4]
It was adopted by the newly formed city in 1816 but somehow fell off seals and official documents and emblems in the early 20th century before being restored to the seal by City Council on July 3, 1950, and signed off by the Mayor on July 7, 1950. Even then, widespread use of the motto was not implemented until city council looked into the matter in November 1958.[5]
Coat of arms and seal
The city of Pittsburgh's coat of arms is based on the arms of William Pitt, the first Earl of Chatham and the city's namesake.[6] The crest of the city's coat of arms serves as a sort of mural crown, featuring an image of a fortress. The Fraternal Order of Police, whose first lodge was founded in Pittsburgh, additionally features the city's coat of arms within its emblem.
The official blazon of the city's coat of arms, as defined by a 1925 city ordinance, is as follows:
On a field Sable, a fess chequay Argent et Azure, between three bezants bearing eagles rising with wings displayed and inverted Or. For crest, Sable a triple-towered castle masoned Argent.[7]
