1.  Homer, Odyssey, 10.510. See Pliny, Natural History, 16.46.110: the willow drops its seed before it is absolutely ripe, and for that reason was called by Homer ‘seed-loser’.

2.  The waters of Lake Clitorius in Arcadia generated an aversion to wine in those who drank of them. See Pliny, Natural History, 31.13.16; Ovid, Metamorphoses, 15.322ff. The combination of the two images here may symbolise minds and characters gone to the bad and producing nothing of value. See Erasmus, Parabolae, p. 268: “As willow-seed, shed before it ripens, is not only itself barren but when used as a drug causes barrenness in women by preventing conception, so the words of those who teach before they have truly learnt sense not only make them no better in themselves, but corrupt their audience and render it unteachable”; and p. 230: “Those who have drunk of the Clitorian Lake develop a distaste for wine, and those who have once tasted poetry reject the counsels of philosophy, or the other way round. Equally, those who gorge themselves with fashionable pleasures reject those satisfactions which are honourable and genuine.”

1.  For pipes of boxwood, see e.g. Ovid, Metamorphoses, 4.30.

2.  The lover should affect pallor and emaciation, as these will soften the lady’s heart; see Ovid, Ars Amatoria, 1.729ff.
