Google has marked the 296th anniversary of the birth of the Italian mathematician and philosopher Maria Gaetana Agnesi with a special doodle.
Among her many achievements, Gaetana Agnesi is credited with being the first woman in the West to gain recognition as a mathematician.
She also believed to have written the first book discussing both differential and integral calculus.
Today's Google doodle features a picture of Gaetana Agnesi with the 'Witch of Agnesi Curve' in the background.
The mathematical curve, which is named after her - but was not discovered by her - was used by mathematicians in later years for work on things like X-rays and electrical circuits.
Gaetana Agnesi was born in Milan on May 16 1718 and quickly became recognised as a child prodigy - speaking Italian, French, Hebrew, Latin, Greek, German and Spanish by the age of eleven.
She was only the second woman in the West ever to be given a professorship at a university.
In later life she devoted herself to studying theology.
She died aged 80 in January 1799.
