Noun [Latin]

IPA: /ˈspek.trum/ [Classical], [ˈs̠pɛkt̪rʊ̃ˑ] [Classical], /ˈspek.trum/ (note: modern Italianate Ecclesiastical), [ˈspɛkt̪rum] (note: modern Italianate Ecclesiastical)
Etymology: From spec(iō) (“look at, behold”) + -trum (making it a doublet of speculum). The only attestation in Classical antiquity is in a pair of letters between Cicero and Cassius Longinus which imply that the Epicurean Catius (fl. c. 50s–40s BC) used spectrum as a translation of the Greek philosophical term εἴδωλον (eídōlon, “image”). It may therefore have been coined by Catius as a neologism, although alternatively, it could be an undocumented but preexisting word that he repurposed as a technical term. After Cicero, the word is extremely sparsely attested until being revived around the start of the sixteenth century by Renaissance humanist authors with the meaning "apparition" or "phantom", possibly influenced by the fact that Greek εἴδωλον also had this sense. The scientific use to refer to the visible spectrum of colored light was first introduced by Isaac Newton, who used the word in the second half of the seventeenth century in both his English writings and in his first Latin draft of the Opticks, the Fundamentum Opticae, although the 1706 Latin translation of Opticks by Samuel Clarke translates Newton's English spectrum into Latin as imago.

It may therefore have been coined by Catius as a neologism, although alternatively, it could be an undocumented but preexisting word that he repurposed as a technical term.\nAfter Cicero, the word is extremely sparsely attested until being revived around the start of the sixteenth century by Renaissance humanist authors with the meaning \"apparition\" or \"phantom\", possibly influenced by the fact that Greek εἴδωλον also had this sense.\nThe scientific use to refer to the visible spectrum of colored light was first introduced by Isaac Newton, who used the word in the second half of the seventeenth century in both his English writings and in his first Latin draft of the Opticks, the Fundamentum Opticae, although the 1706 Latin translation of Opticks by Samuel Clarke translates Newton's English spectrum into Latin as imago.",

Well, even if my eyes were capable of being struck by these 'spectres,' because they spontaneously run in upon them at your will, I do not see how the mind can be struck. You will be obliged to explain it to me, when you return safe and sound, whether the 'spectre' of you is at my command, so as to occur to me as soon as I have taken the fancy to think about you; and not only about you, who are in my heart's core, but supposing I begin thinking about the island of Britain — will its image fly at once into my mind?",

  "etymology_text": "From spec(iō) (“look at, behold”) + -trum (making it a doublet of speculum).\nThe only attestation in Classical antiquity is in a pair of letters between Cicero and Cassius Longinus which imply that the Epicurean Catius (fl. c. 50s–40s BC) used spectrum as a translation of the Greek philosophical term εἴδωλον (eídōlon, “image”). It may therefore have been coined by Catius as a neologism, although alternatively, it could be an undocumented but preexisting word that he repurposed as a technical term.\nAfter Cicero, the word is extremely sparsely attested until being revived around the start of the sixteenth century by Renaissance humanist authors with the meaning \"apparition\" or \"phantom\", possibly influenced by the fact that Greek εἴδωλον also had this sense.\nThe scientific use to refer to the visible spectrum of colored light was first introduced by Isaac Newton, who used the word in the second half of the seventeenth century in both his English writings and in his first Latin draft of the Opticks, the Fundamentum Opticae, although the 1706 Latin translation of Opticks by Samuel Clarke translates Newton's English spectrum into Latin as imago.",

Well, even if my eyes were capable of being struck by these 'spectres,' because they spontaneously run in upon them at your will, I do not see how the mind can be struck. You will be obliged to explain it to me, when you return safe and sound, whether the 'spectre' of you is at my command, so as to occur to me as soon as I have taken the fancy to think about you; and not only about you, who are in my heart's core, but supposing I begin thinking about the island of Britain — will its image fly at once into my mind?",
