3 of Disks
The 3 of Disks is titled "Works" in the Thoth deck and is represented by Mars in Capricorn. In terms of traditional astrology, Mars is exalted in Capricorn. Thus, Mars is well-positioned but, since it is in exaltation rather than being the ruler of Capricorn (Saturn), it is like an honoured guest in Capricorn. The exuberance of Mars is used in a structured manner [per Saturn] in Capricorn. This card depicts exuberant yet structured, productive work. This is also illustrated in, for example, the RWS 3 of Pentacles, where the craftsman works under the direction and planning of the ecclesiastic overseers.
2 of Disks
The 2 of Disks is called "Change" in the Thoth deck and is represented by Jupiter in Capricorn. In traditional astrology, Jupiter is not well-placed in Capricorn as it is in fall in that sign. As astrologer Kevin Burk notes, "Jupiter in Capricorn tends to struggle with issues of lack". As Crowley notes, "the good fortune of Jupiter is very limited [in this placement]". As the yin and yang symbolism in the Thoth 2 of Disks suggests, this card is about dealing with change and observing and assessing the signs of the time, accepting that it's a time of flux. The card could indicate that what used to be a successful way of doing things no longer works as well and needs to be adapted or re-worked; or that the 'when' and 'how' of starting a new venture must be carefully assessed, having regard to the signs of the time.
