Egbert of Liège,
The Well-Laden Ship, tr. Robert Gary Babcock (Cambridge: Harvard University Press, 2013), p. 117 (lines 1093-1096):
CONCERNING POOR SCHOLARLY EFFORT
Scholarly effort is in decline everywhere as never before. Indeed, cleverness is shunned at home and abroad.
What does reading offer to pupils except tears?
It is rare, worthless when it is offered for sale, and devoid of wit.
The Latin (id., p. 116):
DE MALO STUDIO
Ut numquam studium sic friget ubique scolare,
quippe domi sollertia militiaeque negatur;
lectio quid preter plorare ministrat alumnis?
Rara quidem, nauci, cum venerit, et salis expers.
