Hard Rectangle
The shape
A Hard Rectangle takes four planets forming two oppositions. Their ends are joined round the rectangle by two semisquares, about 45°, on the short sides, and two sesquiquadrates, about 135°, on the long sides. Counted among all four planets, that is exactly two oppositions, two semisquares and two sesquiquadrates. It has the same skeleton as the Mystic Rectangle, with the easy aspects swapped for minor hard ones.
A worked example: the Sun at 10° Aries opposes Saturn at 11° Libra, and Mars at 25° Taurus opposes Pluto at 24° Scorpio. Sun–Mars is a semisquare (45°), Saturn–Pluto a semisquare (43°), Sun–Pluto a sesquiquadrate (136°) and Mars–Saturn a sesquiquadrate (136°).
How tight it must be
The semisquare and the sesquiquadrate are minor aspects with a narrow allowance — each counts only within about 2° of exact — and the figure needs four of them at once. A Hard Rectangle is therefore rare, and when one appears it is close.
What it is made of
Two oppositions and four minor hard aspects, all from the eighth-harmonic family (multiples of 45°). Nothing in it is easy. No three of its planets form a named figure, so it contains no smaller one. It sits beside the Grand Cross, the other four-planet figure with no soft aspect in it; the cross is built from squares, this one from the half- and one-and-a-half-squares.
No apex
There is no focal planet, and so no single outlet leads the action. The friction is spread round the four corners and never quite resolves through one of them.
By element or mode
The minor hard aspects do not keep to one element or one mode — a semisquare usually joins neighbouring signs, a sesquiquadrate signs four apart. Read the two oppositions first, by sign and house: they are the axes the friction runs along.
In a chart
A natal Hard Rectangle is read as a persistent working friction: effort kept in motion, matters that are rarely dropped. The caution is a standing sense that the work is never quite finished.
In the sky
In the passing sky the tight orbs make it brief. A transit can complete one with a natal pair of oppositions for a few days, a short period of friction on both axes.
