POTTERY
The earliest Minoan pottery had images carved into the clay. These images were often simple lines filled with simple colors.
Gradually, the Minoans began to paint and/or glaze their pottery. The designs on them went from one or two color to many colors, and the images in the designs became more and more complex. Lines in the early pottery became spirals later, and that progressed to depictions of things in the Minoan's environment, particularly the sea. You can see this progression in the images below.

Interestingly, humans were not portrayed on Minoan pottery. That was reserved for the amazing Minoan fresco paintings.

A fresco is a painting done on wet plaster. Ancient Minoan frescoes, in addition to showing plant and animal life, also showed humans. Usually, the humans depicted in Minoan frescoes are engaged in religious activites, including sporting events. Other frescoes give us a glimpse into daily life of the Ancient Minoans.
One of the most famous Minoan fresco paintings, found in the ruins of the palace at Knossos, shows an event called "bull leaping." In this sport, an acrobat faces a charging bull, grabs it by the horns, and does a somersault over the bull's back. Since bulls are referenced frequently in Minoan and Greek mythology as sacred, it's not a terrible leap to say that bull leaping was probably a sacred event.



SCULPTURE AND JEWELRY
Minoans were also accomplished sculptors and jewelry makers. Like their frescos and pottery, the Minoans honored nature and showed their daily rituals and lives in their sculpture and jewelry.
