Let me recommend The Art of Perfumery And Methods of Obtaining the Odors of Plants by George William Septimus Piesse (published 1857, free download at Project Gutenberg). Some delightful excerpts:
From the Preface: By universal consent, the physical faculties of man have been divided into five senses,—seeing, hearing, touching, tasting, and smelling. It is of matter pertaining to the faculty of Smelling that this book mainly treats. Of the five senses, that of smelling is the least valued, and, as a consequence, is the least tutored; but we must not conclude from this, our own act, that it is of insignificant importance to our welfare and happiness.
From the table of contents for Section I, Introduction & History: Perfumes in use from the Earliest Periods—Origin lost in the Depth of its Antiquity—Possibly derived from Religious Observances—Incense or Frankincense burned in Honor of the Divinities—Early Christians put to Death for refusing to offer Incense to Idols—Use of perfumes by the Greeks and Romans—Pliny and Seneca observe that some of the luxurious People scent themselves Three Times a Day—Use of Incense in the Romish Church—Scriptural Authority for the use of Perfume—Composition of the Holy Perfume—The Prophet’s Simile—St. Ephræm’s Will—Fragrant Tapers—Constantine provides fragrant Oil to burn at the Altars—Frangipanni—Trade in the East in Perfume Drugs—The Art of Perfumery of little Distinction in England—Solly’s admirable Remarks on Trade Secrets—British Horticulturists neglect to collect the Fragrance of the Flowers they cultivate—The South of France the principal Seat of the Art—England noted for Lavender—Some Plants yield more than one Perfume—Odor of Plants owing to a peculiar Principle known as Essential Oil or Otto.
Of ambergris: This substance is found in the sea, floating near the islands of Sumatra, Molucca, and Madagascar; also on the coasts of America, Brazil, China, Japan, and the Coromandel. The western coast of Ireland is often found to yield large pieces of this substance. The shores of the counties of Sligo, Mayo, Kerry, and the isles of Arran, are the principal places where it has been found.
Of civet: In its pure state, civet has, to nearly all persons, a most disgusting odor; but when diluted to an infinitesimal portion, its perfume is agreeable. It is difficult to ascertain the reason why the same substance, modified only by the quantity of matter presented to the nose, should produce an opposite effect on the olfactory nerve; but such is the case with nearly all odorous bodies, especially with ottos, which, if smelled at, are far from nice, and in some cases, positively nasty—such as otto of neroli, otto of thyme, otto of patchouly; but if diluted with a thousand times its volume of oil, spirit, &c., then their fragrance is delightful.
And so on..
