[21] To this period belongs also a fragmentary Fantasia in C minor, preserved in MS. at Berlin.
[22] The inventory of Bach’s property at his death mentions among his books August Pfeiffer’s Anti-Calvinismus. He certainly possessed it at Coethen, as witnesses the inscription on a Clavier-Büchlein written for his second wife.
[23] Their intimate relations may be illustrated by the fact that a child of Bach’s, born in November, 1718, was christened after the Prince and one of his brothers, who with a sister and two courtiers all stood sponsors to the boy.
[24] Bernhard Bach came to occupy his father’s old post at Muehlhausen. He afterwards studied law at Jena, but died there of a fever in 1739.
[25] Spitta, i. 665-669.
[26] A fifth, in A minor, remains in MS. at Berlin.

[28] Add to these three detached minuets printed at 216, pp. 30 f.
[29] An early sonata and two capriccios have already been noticed above, p. 23.
[30] At Weimar he had already written a concerto in C minor, which remains in MS. The arrangements for clavichord of Vivaldi’s violin concertos (217) are of singular interest, as evidence of Bach’s view of the requirements and capacities of the clavichord; but they cannot be included in a list of his original works.
