"He [Callistratus] saith of this yellow Amber, that if it be worne about the necke in a collar, it cureth feavers, and healeth the diseases of the mouth, throat, and jawes: reduced into pouder and tempered with honey and oile of roses, it is soveraigne for the infirmities of the eares. Stamped together with the best Atticke honey, it maketh a singular eyesalve for to help a dim sight: pulverized, and the pouder thereof taken simply alone, or else drunke in water with Masticke, is soveraigne for the maladies of the stomacke." Nicolaus Myrepsus (Recipe 951, _op. citat._) gives a prescription for {36} dysentery and diabetes confiding chiefly of "Electri vel succi Nili (Nili succum appellant Arabes Karabem)."

(Editio Basil., 1556, p. 152), says of amber: "Colligitur in quadam penè insula Sudinorum, qui nunc uoc[=a]tur Brusci, in Prussia, nunc Borussia, juxta Veneticum sinum, & sunt orientaliores ostiis Vistulæ fluuii: ubi triginta pagi huic muneri destinati sunt," etc. He rejects the theory that it consists of hardened gum. There exists an enormous literature concerning Amber and the Prussian amber industry. Amongst the earliest works (after Theophrastus and Pliny) are those of Aurifaber (_Bericht über Agtstein oder Börnstein_, Königsberg, 1551); Goebel (_De Succino, Libri duo, authore Severino Goebelio, Medico Doctore_, Regiomont., 1558); and Wigand (_Vera historia de Succino Borussico_, Jena, 1590). Later on Hartmann, P. J. (_Succini Prussici Physica et civilis Historia_, Francofurti, 1677); and the splendid folio of Nathaniel Sendel (_Historia Succinorum corpora aliena involventium_, Lipsiæ, 1742), with its wealth of plates illustrating amber specimens, with the various included fossil fauna and flora. Georgius Agricola (_De natura Fossilium_, liber iv.), and Aldrovandi (_Musæeum Metallicum_, pp. 411-412) must also be mentioned. Bibliographies of the earlier literature are to be found in Hartmann (_op. citat._), and in Daniel Gralath, _Elektrische Bibliothek_ (_Versuche und Abhandlungen der Naturforschenden Gesellschaft in Danzig_, Zweiter Theil, pp. 537-539, Danzig and Leipzig, 1754). See also Karl Müllenhoff, _Deutsche Altertumskunde_, vol. i., Zweites Buch, pp. 211-224, Zinn und Bernsteinhandel (Berlin, 1870), and Humboldt's _Cosmos_ (Bohn's edition, London, 1860, vol. ii., p. 493). The ancient Greek myth according to which amber was the tears of the Heliades, shed on the banks of the river Eridanus over Phaethon, is not alluded to by Gilbert. It is narrated in well-known passages in Ovid and in Hyginus. Those interested in the modern handling of the myth should refer to Müllenhoff (_op. citat._, pp. 217-223, der Bernsteinmythus), or to that delightful work _The Tears of the Heliades_, by W. Arnold Buffum (London, 1896).
