Properzia is from the Roman family name Propertius. Properzia de' Rossi (c. 1490-1530) was the Italian Renaissance sculptor — *the first female sculptor known to history and the only woman among the artists profiled in Giorgio Vasari's Lives of the Most Eminent Painters, Sculptors, and Architects (1550). Famous for her remarkable miniature sculptures carved on apricot and peach pits including a Crucifixion with 22 figures. Her marble panel of Joseph and Potiphar's Wife is at the Basilica di San Petronio in Bologna.*
Subject of the 2014 Bologna exhibition Properzia de' Rossi: The First Woman Sculptor.
Properzia does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Properzia reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
