As if carrying a torch through the halls of a mountain king, a knight on the stairs of the Crimean Academic Theater in Simferopol - one of the oldest provincial theaters in Russia.

The modern building, however, was built in the early XX century - and the old one that survived with it was demolished during the Soviet years.

Heraldic spolia of Byzantine or Franco-Byzantine origin at the Paleochora complex in Aegina, Greece, the former capital of the island. The town was active from the ancient period well into the Middle Ages.

Today the Orthodox Church, especially Russian, remembers Saint Euphrosyne of Polotsk, a holy princess-nun who not only became the first known bookwoman in Rus', but who generally joined the ranks of the first Christian scholars to enlighten Russia.

Having founded several monasteries in her native city, she also had a lasting and still noticeable influence on Russian architecture - in fact, the old cathedral of the Savior Monastery in Polotsk, built by her care, is the oldest surviving temple where such a characteristic element of Russian architecture as the kokoshniks (usually keeled in their finishing blind arches) appears.

Now, however, we can observe only the zakomaras (semi-circular finishing of Orthodox church walls, which gave origin to kokoshniks) of the first row of kokoshniks - the rest are hidden by a protective neoclassical shell, with which the ancient temple was reinforced in the first half of the XIX century by order of Nicholas I. The Jesuits who seized the monastery, as well as many other monasteries of Belorussia, practically led the temple to destruction - and although the Emperor's intervention saved it and returned it to the Orthodox, it was impossible to restore the pre-Mongolian architecture then.

In our time, however, thanks to the development of new technologies and the preservation of almost all the old masonry in the XIX century, it is possible to fully reconstruct the temple in all its splendor - as was recently restored the ancient Church of the Dormition in Gorodets.

Today we remember the day of Holy Pentecost, when the Holy Spirit descended upon the Apostles. At that time, illumined by divine grace, they were finally transformed from ordinary people - with their weaknesses and sins - into God's messengers - still ordinary people of flesh and blood, but in spirit indestructible and faithful.

In honor of this, the Church has established today a feast in the name of the Holy Trinity, and tomorrow - the Descent of the Holy Spirit upon the Apostles. Today, as always, in honor of the feast, I have prepared a selection of interesting churches dedicated to it.
