These are the lion statues outside the New York Public Library. Named Patience and Fortitude, they have been present since the library was dedicated in 1911.
From the library’s website:
According to Henry Hope Reed in his book, The New York Public Library, about the architecture of the Fifth Avenue building, the sculptor Edward Clark Potter obtained the commission for the lions on the recommendation of Augustus Saint-Gaudens, one of America’s foremost sculptors. Potter was paid $8,000 for the modeling, and the Piccirilli Brothers executed the carving for $5,000, using pink Tennessee marble. After enduring almost a century of weather and pollution, in 2004 the lions were professionally cleaned and restored. Unfortunately, the popular tradition of decorating the lions also endangered them, so the practice has been discontinued on the recommendation of the conservators.
Their nicknames have changed over the decades. First they were called Leo Astor and Leo Lenox, after The New York Public Library founders John Jacob Astor and James Lenox. Later, they were known as Lady Astor and Lord Lenox (even though they are both male lions). During the 1930s, Mayor Fiorello LaGuardia named them Patience and Fortitude, for the qualities he felt New Yorkers would need to survive the economic depression. These names have stood the test of time: Patience still guards the south side of the Library’s steps and Fortitude sits unwaveringly to the north.
As a tribute to the Lions’ popularity and all that they stand for, the Library adopted these figures as its mascots. They are trademarked by the Library, represented in its logo, and featured at major occasions.
