Anyone who is confused by new government advice on how many people can safely and legitimately meet at one time may find some clarity in Henry Purcell’s prescient advice.
Maybe he wrote it during the Great Plague of 1665?
When V and I together meet,
We make up 6 in house or street;
Yet I and V may meet once more,
And then we 2 can make but 4;
But when that V from I are gone.
Alas! poor I can make but 1.
