The Piraeus lion of the Athens harbour was made around 350 BC, around the same time that Plato wrote his dialogues in Athens and taught the "unwritten doctrines", thought to be lost to the world.
When rune symbols were inscribed onto the lion's shoulders in the 11th century the sacred temple sites and learning centres where Linear A and B clay tablets were the source of symbols that were later used as the 24 Elder Futhark, 16 Younger Futhark and 28 Anglo-Saxon Futhork rune alphabets were already demolished, the crusades were about to start. From the 13th century the knowledge about the concepts represented by rune symbols gradually disappeared until there was no memory left of the meaning.
With the new digital revolution ancient scripts and text appear and are translated into English. The first hint is the similarity of numbers used for the rune alphabets that happen to be the same as essential concepts used in Buddhist training of Abhidhamma and meditation: 24 Paṭṭhāna factors, 16 Insight Knowledges and the list of "28 named Buddhas". The rune symbols happen to coincide with concepts still used in meditation training, and when one applies definitions, also described in Old Norse rune poems to runes, it is still possible to develop a set of definitions that can be used to translate the runes, which were used to write votive messages.
The definitions of the runes as chosen coincide with the meaning portrayed by the images, the meaning only appear when they are read together, which makes it plausible that runes were a series of ideograms used to write votive messages, ranging from useful objects to coins and standing stones. The Piraeus lion runes need to be read in conjunction with other texts in the Lost Links series where the background history was thoroughly described, it is an addendum to the Rök rune stone, "Did Pythagoras make the Phaistos DIsk?" and "Etruscan: universal language of the heart".
The Piraues lion is evidence that the unwritten doctrines of Plato were only unwritten, not secret.
