The First Helicopter ? - pillow & tote design by 


My vector drawing and a little bit of imagination, combines Leonardo da Vinci’s 15th century “Aerial Screw” and the Greek geometer Heron’s 1st century steam engine into the world’s first helicopter.

The steam engine was invented by Heron, an ancient Greek geometer and engineer from Alexandria. Heron lived during the first century CE and is sometimes called Hero. Heron made the steam engine and called his device “aeolipile,” which means “wind ball” in Greek. The steam was supplied by a sealed pot filled with water and placed over a fire. Two tubes came up from the pot, letting the steam flow into a spherical ball of metal. The metallic sphere had two curved outlet tubes, which vented steam. As the steam went through the series of tubes, the metal sphere rotated.

I have opened a shop with CafePress to sell some of my designs on clothing, iPhone & laptop cases, jewellery and lots more:
