August 6th: Feast of the Transfiguration

... the feast-day of this blog.

Thou shalt know him when he comes
not by any din of drums
nor the manner of his airs,
nor by anything he wears,
neither by his crown nor his gown.
But his coming known shall be
by the holy harmony
which his coming makes in thee.

[anon, 15-16th century?]
