In the sky

Sualocin is a blue-white star about 254 light-years away, nearly four times the Sun's mass and young as stars go, spinning at about 144 kilometres a second. It is a triple: the primary and a companion circle each other about every seventeen years, and that companion is itself a close pair that turns in thirty days.

It is one of the four stars of the small diamond that makes the Dolphin's body, the figure English country people called Job's Coffin. Its name has no ancient root at all: it is Nicolaus spelled backwards. Niccolò Cacciatore, assistant to Piazzi at Palermo, whose Latin name was Nicolaus Venator, slipped Sualocin and its neighbour Rotanev into the Palermo Catalogue of 1814 as a private signature.

The myth

The Dolphin is Poseidon's messenger. When the sea-nymph Amphitrite fled from his courtship, it was a dolphin that found her and persuaded her to become queen of the sea, and Poseidon set it among the stars in thanks. In the other well-known story a dolphin, drawn by music, carried the singer Arion to shore after sailors had thrown him overboard.

Ptolemy gives the Dolphin the nature of Saturn and Mars and reads a simple appearance, cheerfulness, dissembling and duplicity; Robson adds a fondness for pleasure and travel, and a danger of suffering from ingratitude. The modern writer Noonan gives its bright stars a far kinder Mercury and Jupiter, and the split is worth holding rather than resolving. A dolphin lives between two worlds, breathing air and living in water, and shows a smiling surface over great depth. The old duplicity is the shadow of that doubleness, and beneath it lies the go-between's gift: the one who moves between realms and brings back what was lost.

What it gives

• At home in two elements Manilius promised the Dolphin's children an equal ease on land and sea. The native crosses between worlds — trades, languages, circles, moods — with an agility that makes the crossing look like play.
• The persuader's art The dolphin brought Amphitrite home by persuasion, not by force. This native can carry a proposal across a divide and win agreement where argument would only have hardened the refusal.
• The instinct to rescue The native appears when someone has gone overboard. They hear the call others miss, as the dolphin heard Arion's music, and bring the person to shore with a strength that surprises those who know only their lightness.
• Cheer over the deep The cheerful appearance of the old texts is a real gift. The native keeps a hard crossing bearable with humour and play, and the lightness is honest, because it rides on a depth the native knows well.

What to watch for

• At home nowhere Moving easily between worlds, the native can belong to none of them and spend years without a harbour. The gift returns when one shore is chosen as home and the crossings are made from there.
• Persuasion turned to its own ends The go-between can begin to steer for themselves, and this is where the old duplicity lives. It is restored when the native says plainly, at the outset, where their own interest lies.
• The rescuer's unpaid bill Those who pull others from the water can come to expect thanks and resent its absence, and Robson's ingratitude is most often felt this way. The balance comes back when each rescue is either freely given or its cost spoken aloud at the time.
• The smile as a mask Cheerfulness can become a surface kept up so that no one sees below, and the dissembling of the old texts begins here. The remedy is to let one or two people see the depth under the play, regularly and on purpose.

How to work with it

Name a home shore. Agility between worlds is a strength only when there is a place to return to, and a chosen harbour turns restless movement into voyages with purpose.

Keep the go-between's work transparent. The trust earned by stating one's own stake is worth more than any advantage the silence could have bought.

Let the rescue be a gift or a bargain, never an unspoken debt, and let at least one companion see beneath the cheerful surface.

In brief

Sualocin is the Dolphin's star, carrying a name hidden backwards by an astronomer's assistant. It gives ease in two elements, the persuader's art, the instinct to rescue, and a cheerfulness that rides on real depth. Its risks are the go-between's — belonging nowhere, persuasion bent to private ends, rescues that leave an unpaid bill, and a smile kept up as a mask. The placement works best where the native has a home shore and an open stake, and least well where the playful surface is used to hide what swims beneath it.
