The Tower of Winds

Andronicus of Cyrrhus or Andronicus Cyrrhestes (Greek : Ἀνδρόνικος Κυρρήστου, Andrónikos Kyrrhēstou), son of Hermias, was a Macedonian astronomer who flourished about 100 BC.



He built a horologion at Athens, the so-called Tower of the Winds, a considerable portion of which still exists. It is octagonal, with figures carved on each side, representing the eight principal winds. [1] In antiquity a bronze figure of Triton on the summit, with a rod in his hand, turned round by the wind, pointed to the quarter from which it blew. From this model is derived the custom of placing weather cockorolls on steeples. [2]

Andronikos II Palaiologos Emperor and Autocrat of the Romans

Andronikos II Palaiologos, usually Latinized as Andronicus II Palaeologus, reigned as Byzantine Emperor from 1282 to 1328. Andronikos' reign was marked by the beginning of the decline of the Byzantine Empire. During his reign, the Turks conquered most of the Western Anatolian territories of the Empire and, during the last years of his reign, he also had to fight his grandson Andronikos in the First Palaiologan Civil War. The civil war ended in Andronikos II's forced abdication in 1328 after which he retired to a monastery.

Theodoret of Cyrus or Cyrrhus was an influential theologian of the School of Antioch, biblical commentator, and Christian bishop of Cyrrhus (423–457). He played a pivotal role in several 5th-century Byzantine Church controversies that led to various ecumenical acts and schisms. He wrote against Cyril of Alexandria's 12 Anathemas which were sent to Nestorius and did not personally condemn Nestorius until the Council of Chalcedon. His writings against Cyril were included in the Three Chapters Controversy and were condemned at the Second Council of Constantinople. Some Chalcedonian and East Syriac Christians regard him as a "full" saint. Although the Eastern Orthodox Protopresbyter Michael Pomazansky repeatedly refers to him as "Blessed", there is no evidence in his work that this is the official position of any Eastern Orthodox jurisdiction. Hieromonk Seraphim Rose also refers to Theodoret as "Blessed" in his book The Place of Blessed Augustine in the Orthodox Church while explaining the nature of the term "Blessed" in the Russian Orthodox Church, referring to how both Sts. Augustine and Jerome are referred to as "Blessed" too despite being part of the Orthodox Saints Calendar.

Tower of the Winds Clocktower in Athens, Greece, the worlds first meteorological station

The Tower of the Winds or the Horologion of Andronikos Kyrrhestes is an octagonal Pentelic marble clocktower in the Roman Agora in Athens that functioned as a horologion or "timepiece". It is considered the world's first meteorological station. Unofficially, the monument is also called Aerides, which means Winds. The structure features a combination of sundials, a water clock, and a wind vane. It was supposedly built by Andronicus of Cyrrhus around 50 BC, but according to other sources, might have been constructed in the 2nd century BC before the rest of the forum. In summer of 2014, the Athens Ephorate of Antiquities began cleaning and conserving the structure; restoration work was completed in August 2016.

Senecan tragedy

Senecan tragedy refers to a set of ancient Roman tragedies. Ten of these plays exist, of which most likely eight were written by the Stoic philosopher and politician Lucius Annaeus Seneca. The group includes Hercules Furens, Medea, Troades, Phaedra, Agamemnon, Oedipus, Phoenissae, Thyestes, Hercules Oetaeus, and Octavia. Hercules Oetaeus is generally considered not to have been written by Seneca, and Octavia is certainly not. In the mid-16th century, Italian humanists rediscovered these works, making them models for the revival of tragedy on the Renaissance stage. The two great, but very different, dramatic traditions of the age—French neoclassical tragedy and Elizabethan tragedy—both drew inspiration from Seneca. Usually, the Senecan tragedy focuses heavily on supernatural elements.
