Egyptian blue | The first synthetic pigment in history

Egyptian blue, also known as calcium copper silicate (calcium copper tetrasilicate) or cuprorivaite, is a pigment that was used in ancient Egypt for thousands of years.

It is considered to be the first synthetic pigment.

It was known to the Romans by the name caeruleum.

After the Roman era, Egyptian blue fell from use and, thereafter, the manner of its creation was forgotten.

In modern times, scientists have been able to analyze its chemistry and reconstruct how to make it.

Aristotele: "Love is composed of a single soul inhabiting two bodies"

Aristotele / Ἀριστοτέλης, (Stagira, 384 a.C. o 383 a.C. - Calcide, 322 a.C.) è stato un filosofo Greco antico, ritenuto una delle menti più universali, innovative, prolifiche ed influenti di tutti i tempi, sia per la vastità che per la profondità dei suoi campi di conoscenza.

Insieme a Platone, suo maestro, e a Socrate è considerato uno dei padri del pensiero filosofico occidentale, che però soprattutto da Aristotele ha ereditato problemi, termini, concetti e metodi.
