Laudator Temporis Acti

Erasmus, Adagia II viii 67, in Collected Works of Erasmus, Vol. 34: Adages II vii 1 to III iii 100, translated and annotated by R.A.B. Mynors (Toronto: University of Toronto Press, 1992), p. 77, with notes on p. 342:

Viri senis astaphis calvaria
An old man's skull is as dry as raisins

Ἀνδρὸς γέροντος ἀσταφὶς τὸ κρανίον , An old man's skull is like raisins. The lesson of this adage is that an old man physically is weak and flabby; the juice is drained out of him and his flesh is gone to nothing. Lucian¹ in his Tyrant about old men: 'For they're all just a bunch of raisins.' Grapes when dried are wrinkled and flabby, because the juice has been drained out of them by the sun. Hence the Ancients took also to calling dried-up old men 'raisins' because of their many wrinkles; Lucilius,² cited by Nonius: 'Wrinkled and dry, the old want everything the same.'

67 From the Greek proverb-collections (Zenobius 1.96, Diogenianus 1.85, Suidas A 2190)
1 Lucian] Cataplus 6
2 Lucilius] This line from the early Roman satirical poet Lucilius (557 in Marx's edition, cited by Nonius p 12 Mercier) was added in 1515.

Viri senis astaphis calvaria
Ἀνδρὸς γέροντος ἀσταφὶς τὸ κρανίον, id est
Viri senis velut vua passa cranium.

Admonet adagium invalidum et flaccidum esse senile corpus exhausto succo carnibusque adesis. Lucianus in Tyranno de senibus: Ἐπεὶ ἀσταφίδες γε πάντες ἤδη εἰσί, id est Quandoquidem jam omnes vuae passae sunt. Rugosae enim et flaccidae sunt vuae passae propter succum sole decoctum. Unde veteres et vuas passas vocabant senes passos ob rugositatem. Lucilius citante Nonio:

Rugosi passique senes eadem omnia quaerunt.
