101. See a similar proverb in P. Plowman, C. x. 265, and my note on the
line. The Latin lines quoted in P. Plowman are from Alanus de Insulis,
Liber Parabolarum, cap. i. 31; they are printed in Leyser, Hist. Poet. Med.
Aevi, 1721, p. 1066, in the following form:--
'Sub molli pastore capit lanam lupus, et grex
Incustoditus dilaceratur eo.'
117. _The doctour_, i. e. the teacher; viz. St. Augustine. (There is here
no reference whatever to the 'Doctor' or 'Phisicien' who is supposed to
tell the tale.) In the margin of MSS. E. Hn. is written 'Augustinus'; and
the matter is put beyond doubt by a passage in the Persones Tale, l.
484:--'and, after the word of seint Augustin, it [Envye] is sorwe of other
mannes wele, and Ioye of othere mennes harm.' See note to l. 484.
The same idea is exactly reproduced in P. Plowman, B. v. 112, 113. Cf.
'Inuidus alterius macrescit rebus opimis'; Horace, Epist. i. 2. 57.
