Year: 586 BC

Location Stolen: First Temple, Jerusalem, Israel

Location Lost: Hidden Location Unknown (Whispers point to tunnels beneath Jerusalem, Axum in Ethiopia, or even Tanis in Egypt)

Object Type: Religious Artifact

Description: Said to hold the very stones etched with the Ten Commandments, this golden chest vanished from Jerusalem during a rather unpleasant siege. Whispers claim it was spirited away to a secret resting place, perhaps guarded by more than just dust and time. Finding it would surely be a divine revelation, or at least make for a fantastic story.

Existence: Legend

Year: 106 BC

Location Stolen: Tolosa (Modern Toulouse), France

Location Lost: Along the Via Domitia route between France and Italy (Perhaps buried near a Roman waystation or lost crossing the Rhône?)

Object Type: Gold/Silver Hoard

Description: A proconsul with sticky fingers nabbed this glittering hoard from the town of Tolosa, intending to ferry it back to Rome. Alas, the treasure mysteriously vanished en route, perhaps cursed by its former owners or simply misplaced with spectacular carelessness.

Object Type: Religious Artifact

Description: This magnificent seven-branched candelabrum, looted from Jerusalem's Second Temple, once shone brightly in Rome's Temple of Peace. After a fire ravaged the temple, the Menorah's fate became hazy, like smoke drifting on the wind. Perhaps the Vandals carted it off to Carthage, or maybe it awaits rediscovery in some forgotten Roman vault or beneath the waves.

Location Lost: Beneath the Busento River bed, near Cosenza, Calabria, Italy (Where the river was supposedly diverted)

Object Type: Gold/Silver Hoard

Description: After giving Rome a rather thorough shakedown, the Visigoth king Alaric met an untimely end in southern Italy. His loyal followers supposedly diverted a river, buried him with his immense treasure beneath the riverbed, and then returned the waters to hide the spot forever. Beneath the currents of the Busento, a king's ransom might still lie entombed for someone clever enough to look.

Location Lost: Unknown (Possibly hidden in the Zagros Mountains, Iran, or scattered across former Persian territories)

Object Type: Royal Treasure Hoard

Description: One of eight legendary treasures belonging to the Sasanian king Khosrow II, its name hints at a 'windfall' of unimaginable riches. Like many tales spun from the opulent threads of ancient Persia, its exact contents and location are lost to myth. Perhaps it was scattered by conquest, or maybe it waits in a hidden mountain vault dreamt up by storytellers and findable by the persistent.

Location Lost: Unknown (Possibly hidden within a later Imperial tomb, buried near a former capital, or even smuggled out of China)

Object Type: Imperial Regalia

Description: Crafted by China's first emperor, this jade seal was the ultimate symbol of imperial authority, passed down through dynasties like a divine mandate. During the chaotic Five Dynasties period, however, it vanished from the historical record, leaving emperors scrambling for legitimacy.

Object Type: Weaponry / Imperial Regalia

Description: One of Japan's three sacred treasures, this legendary sword grants legitimacy to the Emperor but took an unfortunate dip during a 12th-century sea battle. Though officials claim a replica (or perhaps the original?) rests safely in a shrine, they're rather shy about letting anyone peek. Is the true Kusanagi slumbering beneath the waves, findable by submersible, or hiding behind priestly robes?

Existence: Legend

Year: 1216 AD

Location Stolen: N/A (Lost in transit)

Location Lost: The Wash estuary, near Sutton Bridge, Lincolnshire, England (Swallowed by quicksand/tides)

Object Type: Crown Jewels

Description: Poor King John, already unpopular, managed to lose his entire baggage train – crown jewels included – in the treacherous tidal estuary known as The Wash.

Object Type: Crown Jewels / Royal Regalia

Description: The symbol of the last sovereign Prince of Wales, this coronet was seized by Edward I and stored with England's jewels in Westminster Abbey. However, during a brazen theft in 1303, it vanished, seemingly slipping through history's fingers more effectively than the other stolen items. Unlike its English counterparts destroyed later, this Welsh crown simply ceased to be mentioned, perhaps hidden nearby awaiting a Welsh revival.

Much of the looted treasure sank into the canals and lake surrounding Tenochtitlan as the soldiers fled for their lives. Beneath the streets and subways of modern Mexico City, Aztec gold might still lie buried, waiting for urban explorers.

Existence: Partially Confirmed

Description: Thought to be the biggest bell ever cast, this bronze behemoth was pinched from the Shwedagon Pagoda by a Portuguese mercenary hoping for cannon fodder. Unfortunately for him, the bell proved too mighty for his flagship, dragging it to the bottom of the river confluence. There it remains, a monumental loss slumbering beneath the muddy waters, perhaps locatable with advanced sonar.

Description: Spanish gold meant to fuel the Jacobite rising arrived too late for the Battle of Culloden, leading to frantic efforts to hide the funds from Hanoverian forces. Parcels of coins were allegedly squirrelled away around the shores and islands of Loch Arkaig, guarded by loyal Highlanders. Though some was recovered or spent, whispers persist that Jacobite gold still lies buried beneath the Scottish heather, waiting for a true believer.

Location Lost: Unknown (Possibly hidden within Paris, smuggled out of France, or melted down)

Object Type: Royal Regalia

Description: Considered perhaps the oldest piece of the French crown jewels, this 7th-century sceptre represented centuries of royal power. It rested safely in the Basilica of Saint-Denis until the French Revolution's chaos provided cover for its theft in 1795. Unlike other regalia melted down, this ancient symbol simply vanished, perhaps tucked away in a Parisian antique shop or a collector's hidden vault.
