Barye strove for anatomical accuracy in his sculptures, and his watercolors show his interest, shared with Delacroix, in the physiological similarities between humans and wild cats. A painting and print by Delacroix, from 1830 and 1831, respectively, may have inspired the feline family grouping seen here. Barye and Delacroix also spent time drawing animals from life at the Jardin des Plantes. Access to sketch the zoo animals was not guaranteed unless, like Barye and Delacroix, one knew the director; the fascinated public applied in droves for tickets when a giraffe entered the menagerie in 1827.
