J. Barrie Jones suggests that "amongst the works that Chopin intended for concert use, the four ballades and four scherzos stand supreme", and adds that "the Barcarolle Op. 60 stands apart as an example of Chopin's rich harmonic palette coupled with an Italianate warmth of melody." Temperley opines that these works, which contain "immense variety of mood, thematic material and structural detail", are based on an extended "departure and return" form; "the more the middle section is extended, and the further it departs in key, mood and theme, from the opening idea, the more important and dramatic is the reprise when it at last comes."
What does J. Barrie Jones feel stands supreme of Chopin's concert pieces?
the four ballades and four scherzos

Very few early Byzantine mosaics survived the Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church, which were made between 634 and 730, also escaped destruction. Unusually almost all represent Saint Demetrius of Thessaloniki, often with suppliants before him.
When were the panels in the Hagios Demetrios Church created?
between 634 and 730

When Pasternak stopped producing Durbin's pictures, and she outgrew her screen persona and pursued more dramatic roles, the studio signed 13-year-old Gloria Jean for her own series of Pasternak musicals from 1939; she went on to star with Bing Crosby, W. C. Fields, and Donald O'Connor. A popular Universal film of the late 1930s was Destry Rides Again (1939), starring James Stewart as Destry and Marlene Dietrich in her comeback role after leaving Paramount Studios.
