Heathen Review: Piero di Cosimo’s Renaissance Art
Renaissance artist and Florentine Piero di Cosimo’s first major exhibit in 500 years is at the National Gallery of Art in Washington D.C., which means it’s time for a heathen review.
Heathen Observations:
This exhibit contains 44 of Piero di Cosimo’s paintings. Glimpses of just a few show that Renaissance distribution networks were not sufficient to provide all members of society with adequate shirtwear. While most men, as long as they weren’t drunk or half-beasts, were consistently able to acquire shirts from Medici, Inc, only women in close proximity to electrostatic head netting were permitted shirtwear that completely covered their bosom. The bosoms of most women were partially exposed during the Renaissance. In the presence of water but no electrostatic head netting, a woman’s bosom was fully exposed.
Heathen Questions:
Does the electro-static head netting create a force field that helps Renaissance women keep their shirts on? Why don’t all women wear the electrostatic netting? What unsung Renaissance genius learned to harness electricity before William Gilbert made his careful study of electricity and magnetism in 1600?
Heathen Concerns:
- Temperature control – In January, the average temperature of Florence, Italy, is 34 degrees Fahrenheit. That’s too cold not to be wearing a scarf much less to have your decollatage exposed.
- Sunburn and cancer risk – During the summer, the city of Florence experiences as much as fifteen hours of sunlight daily. If distribution networks couldn’t accomplish shirtwear for all, it’s extremely unlikely women had access to SPF 40 and above sunscreen with both UVA and UVB protection.
- Giving credit where credit is due – One woman’s true shirt-retention genius has gone unacknowledged for too long.

Heathen Conclusion:
The first person to discover the miracle of electrostatic head netting has been hiding in plain sight for 500 years. Often holding a baby, she features prominently in many Renaissance images and is usually referred to as “Mary.” Careful observation of di Cosimo’s work makes clear “Mary” discovered that rubbing a child against her clothing generated an electrostatic charge that powered her head netting and helped keep her shirt on. It’s not clear how “Mary” acquired her first shirt, but that’s a mystery for another heathen researcher to solve. Sadly, “Mary’s” discoveries were not adequately disseminated, and millions of women were unable to stay warm and sunburn-free through use of the acquired shirt / rubbed child / electrostatic hair netting / keep-your-shirt-on cycle. Luckily, like the transit from proto-bacteria to complex organisms with 37 trillion cells, knowledge of how to keep your shirt on evolved via other pathways. We should all take a moment to acknowledge the unsung genius of “Mary,” an early electricity pioneer.
