All things at the end of time become amethyst ...
Amethyst is a violet-coloured variety of quartz; i.e., a hard crystalline mineral made from silica (SiO2). It owes its beauty - as do most things - to its imperfections; namely, impurities of iron and the presence of other trace elements, including, if Remy Belleau is to be believed, a few drops of sacred wine [1].
It's also, according to astrologers, my birthstone. Which is somewhat awkward for a Dionysian philosopher, as the English name derives from the Hellenistic Greek term amethystos [αμέθυστος], meaning unintoxicated (a reference to the belief that wearing the semi-precious stone protected its owner from drunkenness).
However, it's important to remember that even Nietzsche - the major disciple of Dionynsus in the modern world - doesn't approve of piss-heads, placing alcohol alongside Christian morality as one of the two great European narcotics and who, for the most part, drank only water, preferring as he did to keep both a clear-head and a cool-head (as I do).
Ultimately, whilst Nietzsche admired the transfiguring power of intoxication, he strongly recommended that all spiritual natures abstain from alcohol and he didn't sacrifice human reason in the name of a wild irrationalism. Throughout his writings, cognitive activity is itself conceived as a drive of some kind, or even a form of passion; the will to make an intrinsically chaotic world intelligible and thus a world we might inhabit with a degree of security.
And, for Nietzsche, whilst not denying the ecstatic element of the Dionysian experience, the god speaks differently to him: he speaks of this world (as the only world); of love as an earthly reality and of the eternal delight of existence in all of its aspects (even the most terrible) [2].
Notes
[1] In his poem L'Amethyste, ou les Amours de Bacchus et d'Amethyste, 16th-century French poet Remy
Belleau invents a myth in which Bacchus - the Roman version of
Dionysus - was pursuing a maiden named Amethyste,
who refused his affections and called on Diana to safeguard her chastity. This the goddess did by transforming Amethyste into a pure white gemstone. Impressed by the girl's determination to remain chaste, Bacchus pours wine over her new mineral form as an offering, thereby staining the crystal purple.
[2] In a note from 1888, for example, Nietzsche writes:
"Philosophy, as I have hitherto
understood and lived it, is a voluntary quest for even the most
detested and notorious sides of existence. [...] Such an experimental philosophy [...] wants [...] a Dionysian affirmation of
the world as it is, without subtraction, exception, or selection - it
wants the eternal circulation: the same things, the same logic
and illogic of entanglements. The highest state a philosopher can
attain: to stand in a Dionysian relationship to existence - my formula for this is amor fati."
