The "Karditsa Thinker" is a Neolithic clay figurine found in the area of Karditsa in Thessaly, Greece. This unique artifact, dating back to the Final Neolithic period (4500-3300 B.C.), is a large solid clay figurine of a seated man. Despite some clumsiness in detail, it conveys the impression of a robust man looking upwards with a manly bearing. The figurine exhibits features of fully developed sculpture and is considered the largest Neolithic artifact found in Greece. The pronounced ithyphallic element, though mostly broken, along with its size, suggests a possible cultic character, possibly representing an agrarian deity associated with the fertility of the land.The Thinker from Yehud, also known as the Thinker of Palestine, is an archaeological figurine discovered during salvage excavations in the Israeli city of Yehud. The figurine, which sits atop a ceramic jug in a posture resembling "The Thinker," dates back to the Middle Bronze Age II Palestine (c. 1800–1600 B.C.E.). It was found in a tomb accompanied by various items, including daggers, spearheads, an axe head, a knife, two male sheep, and a donkey, all likely buried as offerings. After its discovery, the broken jug had to be stabilised and restored before being displayed in the Canaanite Galleries of the Israel Museum in Jerusalem.The "Thinker of Cernavodă", Romania, a terracotta sculpture, and its female counterpart, "The Sitting Woman", are works of art from the Chalcolithic era. The Hamangia culture produced these remarkable sculptures, with The Thinker believed to be the earliest prehistoric sculpture that conveys human self-reflection instead of the more common artistic themes of hunting or fertility. The discovery of the Spong Man, which is the earliest known Anglo-Saxon sculpture of a person, was found in Europe's other end, five millennia. The sculpture takes the form of a seated figure on a pottery lid of a cremation urn, resembling a humanoid figure.
A thousand years later, Michelangelo created the tomb of Lorenzo de' Medici, Duke of Urbino, which is located in the Basilica di San Lorenzo in Florence, Italy. The tomb is a sculptural masterpiece and was commissioned by Pope Clement VII to honor the memory of the Duke of Urbino, a member of the powerful Medici family of Florence. The tomb is considered one of Michelangelo's finest works in sculpture and was created in the Mannerist style of the Late Renaissance period. The tomb features a large rectangular base, which is adorned with intricate reliefs and two sculptures, Dusk and Dawn, that represent the cycle of life. The central figure on the tomb is a sculpture of the Duke, who is portrayed as a thinker with his face in shadow and his elbow resting on a money box with a similarly muscular, contemplative figure with his hand on his chin, though the figure is seated rather than standing like Rodin's "The Thinker.". The tomb also includes two reclining figures on the sarcophagus, which are believed to represent Day and Night.
