General Book of the Tarot, by A. E. Thierens, [1930], at sacred-texts.com
TRADITION: Solitude, retreat, hermitage, exile, isolation, inhibited condition, abandonment. Tomb and coffin. Reversed: Economy, good conduct, circumspection, precaution, wise administration, testament, avarice, household, savings, order, etc.
THEORY: The element of Earth on the Fourth house, house of the home and the sign Cancer. This immediately explains why this card has been said to stand for economy, savings, even avarice and household affairs as well as for many things in connection with the end of life, since the fourth house in the horoscope relates to the end of life, and to the inner side of life as long as this lasts. Tradition is
once more very correct in this case. When it enumerates "concord, harmony, etc.," amongst the synonyms of this card, however, there is some discrepancy, because the only thing that can be meant here is 'repose' or the condition of rest, as that of the grave, in which external differences are lost. So taken in the strictly etymological sense of the words, 'concord,' etc., have nothing to do with it. If in any case this card should relate to business, it certainly does not mean that anything like accord has been or will be reached, but that one of the parties retires or takes his proposals back. It may also relate to the condition of the soul, in which one harvests the results of material life in the world, whether spiritually, by meditation, or materially, by economy. In any case it points to a stillness and heavy condition of the mind. Further, to the tendency of collecting, gathering.
CONCLUSION: Solitude, repose, retreat, retiring from the world, "hermit's repose" (W.); gathering, collecting, taking home one's savings or impressions, meditation, economy, avarice, precaution, testament, and the place occupied at the end of life, hermitage, grave, coffin. The place of the card in the horoscopic scheme indeed suggests the idea of being buried under the earth.
