One obstacle is even if we do know the future, what can we do to stop what will be? Can anything be done at all? Are all things just fated to occur? Is there a rational behind the universe. Is the future written as it occurs or in advance?
In Roman mythology, Fortuna (equivalent to the Greek goddess Tyche) was the personification of luck, hopefully of good luck, but she could be represented veiled and blind, as modern depictions of Justice are seen, and came to represent the capriciousness of life.
Fortuna had a retinue that included Copia among her blessings. Under the name Annonaria she protected grain supplies. In the Roman calendar, June 11 was sacred to Fortuna, with a greater festival to Fors Fortuna on the 24th.
Fortuna was propitiated by mothers. Traditionally her cult was introduced to Rome by Servius Tullius. Fortuna had a temple in the Forum Boarium, a public sanctuary on the Quirinalis, as the tutelary genius of Roma herself, Fortuna Populi Romani, the "Fortune of the Roman people", and an oracle in Praeneste where the future was chosen by a small boy choosing oak rods with possible futures written on them.
All over the Roman world, Fortuna was worshipped at a great number of shrines under various titles that were applied to her according to the various circumstances of life in which her influence was hoped to have a positive effect. Fortuna was not always positive: she was doubtful (Fortuna Dubia); she could be "fickle fortune" (Fortuna Brevis), or downright evil luck (Fortuna Mala).
Her name seems to derive from the Italic goddess Vortumna, "she who revolves the year".
From Carmina Burana
Fortune plango vulnera I bemoan the wounds of Fortune
stillantibus ocellis with weeping eyes,
quod sua michi munera for the gifts she made me
subtrahit rebellis. she perversely takes away.
Verum est, quod legitur, It is written in truth,
fronte capillata, that she has a fine head of hair,
sed plerumque sequitur but, when it comes to seizing an opportunity
Occasio calvata. she is bald.
In Fortune solio On Fortune's throne
sederam elatus, I used to sit raised up,
prosperitatis vario crowned with
flore coronatus; the many-coloured flowers of prosperity;
quicquid enim florui though I may have flourished
felix et beatus, happy and blessed,
nunc a summo corrui now I fall from the peak
gloria privatus. deprived of glory.
Fortune rota volvitur: The wheel of Fortune turns;
descendo minoratus; I go down, demeaned;
alter in altum tollitur; another is raised up;
nimis exaltatus far too high up
rex sedet in vertice sits the king at the summit -
caveat ruinam! let him fear ruin!
nam sub axe legimus for under the axis is written
Hecubam reginam. Queen Hecuba.
