Hierapolis in the context of "Sawmill"

Epictetus (/ˌɛpɪkˈtiːtəs/, EH-pick-TEE-təss; Ancient Greek: Ἐπίκτητος, Epíktētos; c. 50 – c. 135 AD) was a Greek Stoic philosopher. He was born into slavery at Hierapolis, Phrygia (present-day Pamukkale, in western Turkey) and lived in Rome until his banishment, after which he spent the rest of his life in Nicopolis in northwestern Greece.

Epictetus studied Stoic philosophy under Musonius Rufus and after manumission, his formal emancipation from slavery, he began to teach philosophy. When philosophers were banished from Rome by Emperor Domitian toward the end of the first century, Epictetus founded a school of philosophy in Nicopolis. He taught that philosophy is a way of life and not simply a theoretical discipline. To Epictetus, all external events are beyond our control; he argues that we should accept whatever happens calmly and dispassionately. However, he held that individuals are responsible for their own actions, which they can examine and control through rigorous self-discipline. His teachings were written down and published by his pupil Arrian in his Discourses and Enchiridion. They influenced many later thinkers, including Marcus Aurelius, Pascal, Diderot, Montesquieu, Rabelais, and Samuel Johnson.

The Hierapolis sawmill was a water-powered stone sawmill in the Ancient Greek city of Hierapolis in Roman Asia (modern-day Turkey). Dating to the second half of the 3rd century AD, the sawmill is considered the earliest known machine to combine a crank with a connecting rod to form a crank-slider mechanism.

The watermill is evidenced by a raised relief on the sarcophagus of a certain Marcus Aurelius Ammianos, a local miller. On the pediment a waterwheel fed by a mill race is shown powering via a gear train two frame saws cutting rectangular blocks by the way of connecting rods and, through mechanical necessity, cranks (see diagram). The accompanying inscription is in Greek and attributes the mechanism to Ammianos' "skills with wheels".

Pamukkale, (Turkish pronunciation: [paˈmuk̚kale]) meaning "cotton castle" in Turkish, is a natural site in Denizli Province in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing of thermal spring water. It is located in Turkey's Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.

The ancient Greek city of Hierapolis was built on top of the travertine formation which is in total about 2,700 metres (8,860 ft) long, 600 m (1,970 ft) wide and 160 m (525 ft) high. It can be seen from the hills on the opposite side of the valley in the town of Denizli, 20 km away. This area has been drawing visitors to its thermal springs since the time of classical antiquity. The Turkish name refers to the surface of the shimmering, snow-white limestone, shaped over millennia by calcite-rich springs. Dripping slowly down the mountainside, mineral-rich waters collect in and cascade down the mineral terraces, into pools below.
