Among the many artefacts left behind at the closure of this masonic centre, one of the more interesting was a typed script for a masonic ceremony. Attempting to decode the script with its mysterious redactions and abbreviations was a fun challenge. It appears that a candidate for a degree of freemasonry is given the role of Third Sojourner in a play acted out over the chessboard-tiled floor. Three sojourners have recently come out of captivity in Babylon, and offer their masonry skills acquired during forced labour to the Sanhedrin – an assembly of Jewish rabbis – to assist with building the second temple of Solomon. After convincing the Sanhedrin of their genuine intentions, they are employed and dispatched to the site of the build. They are given rudimentary tools – a pickaxe, shovel and crowbar, safety ropes and explicit instructions to keep secret any artefacts they uncover from Solomon’s first temple, which according to Jewish tradition was destroyed by Nebuchadnezzar II in 587 BCE. Unsurprisingly, they do make a string of discoveries in a plot as preordained as an episode of CSI: a pickaxe loosens up the earth and reveals a hollow sound beneath; a shovel clears away the earth to uncover the crown of a stone arch; its central keystone has a ring attached; a crowbar happens to perfectly fit that ring and allows the keystone to be lifted to reveal an engraving on it signposting a path to hidden treasure; lots are drawn to determine which sojourner descends into the dark cavity with the rope “cable tow” around his waist in case he meets danger and needs to be hauled up by his companions; the air he finds below is indeed poisonous and the dark is pervasive, so they wait for the illumination of the rising sun and the dissipation of the foul air; the second sojourner descends and retrieves a scroll (which according to another online source is the last remaining copy of a book of holy law hidden during Nebuchadnezzar’s siege of Jerusalem); the three sojourners bind themselves to secrecy, and led by the third sojourner they make one final descent as the sun reaches its high meridian; they find a beautiful subterranean chamber and another arch made of marble, banners bearing names, and other peculiar “signs”.

As the three sojourners close up the vault, obscure its point of entry, and resolve to return the scroll, a hand drawing of the underground chamber and word of their other discoveries to the Sanhedrin, they demonstrate values and practices considered worthy of a freemason. In many respects these values and practices are not dissimilar to the ways of urban explorers. We understand the thrill of discoveries made while fossicking through the forgotten, dark cavities of the modern city. We too make sure the whole crew gets out safe. Like freemasons we swear each other to secrecy, albeit somewhat less formally. And we can also exhibit a similar tribalism founded on knowledge mindfully shared and withheld.
