1. Galileo's first sketches of the moon after viewing it through his telescope in 1609.
2. The Moon based on a watercolor by Galileo (left), alongside a modern photograph of the same lunar phase.
This was published in Sidereus Nuncius, a short astronomical treatise written in Neo-Latin by Galileo and published on March 13, 1610.
3. Drawings of the sunspots
Using a brilliant projecting device, the so-called helioscope, Galileo managed to draw the sunspots with almost photographic accuracy, yet without risking damaging his eyesight through direct observation of the Sun's disc.
Regarded as one of the most iconic fountains in the world, it was designed by the Italian architect Nicola Salvi and completed by Giuseppe Pannini in 1762.
Its name derives from the Latin word trivium, meaning "intersection of three streets".
3. The Colosseum
It is thought that the name originates from a massive statue of Nero, which was moved beside the amphitheatre by the emperor Hadrian.
The word colosseum is a neuter Latin noun formed from the adjective colosseus, meaning "gigantic" or "colossean".
Located on Piazza San Nicola, the church was built in 1719 in the Baroque style with an octagonal layout.
It received "monument" status for its magnificent majolica floor mosaic.
3. Siena Cathedral's marble mosaic floor
Crafted over centuries (14th–19th), it’s one of Italy’s most ornate masterpieces.
Giorgio Vasari, often referred to as the father of art history, claimed Siena's floor was “the most beautiful, great and magnificent pavement ever made.”
