On 6 July 2022, the Georgia Guidestones, a granite monument built in 1980 by an anonymous group, was partially destroyed in a bombing and demolished within hours. For over four decades, the monument’s ten inscribed guidelines for rebuilding civilisation had sparked fierce debate: were they visionary or sinister? The identity of its commissioner, who called himself R.C. Christian, remains unknown. Meanwhile, on 6 July 2003, Ukraine’s Yevpatoria Planetary Radar transmitted Cosmic Call 2, a message aimed at five distant stars that won’t arrive until 2036 at the earliest. Back in 1348, on this same date, Pope Clement VI issued a papal bull defending Jewish communities against plague-related persecution, a rare act of moral clarity during the Black Death. And in 1411, Admiral Zheng He returned to Nanjing from his third treasure voyage, bringing with him the captured king of Kotte. Four stories about messages, monuments, courage, and the questions history leaves unanswered.
