four to six in the afternoon
In Ravenna , as has been said , a great reception of all the society at the Palazzo Castelmare on the Sunday evening was as much an institution as the High Mass on a Sunday morning . And this was the course of things during all the year , except in Carnival time . Then , in order to leave Sunday evening -- the great time for balls and theatres , and pleasure of all sorts free , the reception at the Palazzo Castelmare was changed to the Monday . The programme , therefore , for the three last grand days of the Carnival in Ravenna , on that occasion , stood thus : -- On the Sunday , a grand gala Corso from four to six in the afternoon . -LRB- That is to say , that every available carriage of every sort in Ravenna would be put in requisition , and would be driven in procession , at a slow foot pace , up and down the long street called the Corso ; and those who had servants and liveries and fine horses would display them and rejoice ; and those who had none of these things would mingle with the grand carriages in broken-down shandridans , and rejoice also at the sight of the finery , without the smallest feeling of shame at their own poverty . This is a Corso . -RRB- On the Sunday evening , the grand representation of the Sonnambula , with the theatre lighted -LRB- according to advertisement -RRB- `` with wax-candles , till it was as light as day !
