The Mass for five voices, written by William Byrd about the year 1588, is one of the most beautiful productions of that extraordinary period, and is sufficient in itself to prove that music in England, like her literature, could then challenge comparison with that of any country whatever, either for beauty or originality. It may be mentioned here that Byrd never swerved from his allegiance to the Roman Catholic Church. It has been said that there is no proof that Tallis changed his faith, but the fact that he was requisitioned to set music for the new services to English words seems to me perfectly conclusive that he did acquiesce in the new order of things. In those troublous days there were comparatively few who dared openly to adhere to the Catholic Church--that is to say, to the Church as it was before Henry VIII. repudiated allegiance to the Pope--the many submitted to the behests of the day and declared themselves definitely on the side they thought would eventually become ascendant, always, however, endeavouring to secure a loophole of escape in case they should find that they had, to use the famous Marquis of Salisbury's well-known phrase, "put their money on the wrong horse." These words may suggest a more sinister idea than they are intended to convey, but their significance will soon be made clear. It must be remembered that when Henry cast off the supremacy of Rome--for reasons it is not necessary to enter upon here--with one or two exceptions, no repudiation of the general tenets of the Catholic Church was insisted upon. In fact, like his wonderful daughter, Queen Elizabeth, he was averse, with characteristic Tudor caution, to cataclysmic changes which might once more divide his kingdom into two great opposing camps, such as it had only recently escaped from. On the contrary, having achieved the personal ends he had in view, he desired nothing better than that things should calm down and proceed on the same lines, as nearly as possible, as they had before, without the masses of the people recognising or understanding the true import of what had taken place. Had he been succeeded by Elizabeth, this policy might have been successful, and many a disastrous page of history would probably never have had to be written. His dominating personality sufficed to avert any open rebellion to his will, but on his death the succession to the throne of a sickly boy, whose fanatical spirit had been fired by still more fanatical advisers, was the signal for an outburst of Puritanical frenzy.
