  The　learned　Nicholas　Perotti　gives　the　earliest　account　of　this　strange　disorder。　　Nobody　had　the　least　doubt　that　it　was　caused　by　the　bite　of　the　tarantula；　a　ground…spider　common　in　Apulia：　and　the　fear　of　this　insect　was　so　general　that　its　bite　was　in　all　probability　much　oftener　imagined；　or　the　sting　of　some　other　kind　of　insect　mistaken　for　it；　than　actually　received。　　The　word　tarantula　is　apparently　the　same　as　terrantola；　a　name　given　by　the　Italians　to　the　stellio　of　the　old　Romans；　which　was　a　kind　of　lizard；　said　to　be　poisonous；　and　invested　by　credulity　with　such　extraordinary　qualities；　that；　like　the　serpent　of　the　Mosaic　account　of　the　Creation；　it　personified；　in　the　imaginations　of　the　vulgar；　the　notion　of　cunning；　so　that　even　the　jurists　designated　a　cunning　fraud　by　the　appellation　of　a　〃stellionatus。〃　Perotti　expressly　assures　us　that　this　reptile　was　called　by　the　Romans　tarantula；　and　since　he　himself；　who　was　one　of　the　most　distinguished　authors　of　his　time；　strangely　confounds　spiders　and　lizards　together；　so　that　he　considers　the　Apulian　tarantula；　which　he　ranks　among　the　class　of　spiders；　to　have　the　same　meaning　as　the　kind　of　lizard　called　＇Greek　text＇；　it　is　the　less　extraordinary　that　the　unlearned　country　people　of　Apulia　should　confound　the　much…dreaded　ground…spider　with　the　fabulous　star…　lizard；　and　appropriate　to　the　one　the　name　of　the　other。　　The　derivation　of　the　word　tarantula；　from　the　city　of　Tarentum；　or　the　river　Thara；　in　Apulia；　on　the　banks　of　which　this　insect　is　said　to　have　been　most　frequently　found；　or；　at　least；　its　bite　to　have　had　the　most　venomous　effect；　seems　not　to　be　supported　by　authority。　　So　much　for　the　name　of　this　famous　spider；　which；　unless　we　are　greatly　mistaken；　throws　no　light　whatever　upon　the　nature　of　the　disease　in　question。　　Naturalists　who；　possessing　a　knowledge　of　the　past；　should　not　misapply　their　talents　by　employing　them　in　establishing　the　dry　distinction　of　forms；　would　find　here　much　that　calls　for　research；　and　their　efforts　would　clear　up　many　a　perplexing　obscurity。
  Perotti　states　that　the　tarantulathat　is；　the　spider　so　called　was　not　met　with　in　Italy　in　former　times；　but　that　in　his　day　it　had　become　common；　especially　in　Apulia；　as　well　as　in　some　other　districts。　　He　deserves；　however；　no　great　confidence　as　a　naturalist；　notwithstanding　his　having　delivered　lectures　in　Bologna　on　medicine　and　other　sciences。　　He　at　least　has　neglected　to　prove　his　assertion；　which　is　not　borne　out　by　any　analogous　phenomenon　observed　in　modern　times　with　regard　to　the　history　of　the　spider　species。　　It　is　by　no　means　to　be　admitted　that　the　tarantula　did　not　make　its　appearance　in　Italy　before　the　disease　ascribed　to　its　bite　became　remarkable；　even　though　tempests　more　violent　than　those　unexampled　storms　which　arose　at　the　time　of　the　Black　Death　in　the　middle　of　the　fourteenth　century　had　set　the　insect　world　in　motion；　for　the　spider　is　little　if　at　all　susceptible　of　those　cosmical　influences　which　at　times　multiply　locusts　and　other　winged　insects　to　a　wonderful　extent；　and　compel　them　to　migrate。
  The　symptoms　which　Perotti　enumerates　as　consequent　on　the　bite　of　the　tarantula　agree　very　exactly　with　those　described　by　later　writers。　　Those　who　were　bitten；　generally　fell　into　a　state　of　melancholy；　and　appeared　to　be　stupefied；　and　scarcely　in　possession　of　their　senses。　　This　condition　was；　in　many　cases；　united　with　so　great　a　sensibility　to　music；　that　at　the　very　first　tones　of　their　favourite　melodies　they　sprang　up；　shouting　for　joy；　and　danced　on　without　intermission；　until　they　sank　to　the　ground　exhausted　and　almost　lifeless。　　In　others；　the　disease　did　not　take　this　cheerful　turn。　　They　wept　constantly；　and　as　if　pining　away　with　some　unsatisfied　desire；　spent　their　days　in　the　greatest　misery　and　anxiety。　　Others；　again；　in　morbid　fits　of　love；　cast　their　longing　looks　on　women；　and　instances　of　death　are　recorded；　which　are　said　to　have　occurred　under　a　paroxysm　of　either　laughing　or　weeping。
  From　this　description；　incomplete　as　it　is；　we　may　easily　gather　that　tarantism；　the　essential　symptoms　of　which　are　mentioned　in　it；　could　not　have　originated　in　the　fifteenth　century；　to　which　Perotti's　account　refers；　for　that　author　speaks　of　it　as　a　well…　known　malady；　and　states　that　the　omission　to　notice　it　by　older　writers　was　to　be　ascribed　solely　to　the　want　of　education　in　Apulia；　the　only　province　probably　where　the　disease　at　that　time　prevailed。　　A　nervous　disorder　that　had　arrived　at　so　high　a　degree　of　development　must　have　been　long　in　existence；　and　doubtless　had　required　an　elaborate　preparation　by　the　concurrence　of　general　causes。
  The　symptoms　which　followed　the　bite　of　venomous　spiders　were　well　known　to　the　ancients；　and　had　excited　the　attention　of　their　best　observers；　who　agree　in　their　descriptions　of　them。　　It　is　probable　that　among　the　numerous　species　of　their　phalangium；　the　Apulian　tarantula　is　included；　but　it　is　difficult　to　determine　this　point　with　certainty；　more　especially　because　in　Italy　the　tarantula　was　not　the　only　insect　which　caused　this　nervous　affection；　similar　results　being　likewise　attributed　to　the　bite　of　the　scorpion。　　Lividity　of　the　whole　body；　as　well　as　of　the　countenance；　difficulty　of　speech；　tremor　of　the　limbs；　icy　coldness；　pale　urine；　depression　of　spirits；　headache；　a　flow　of　tears；　nausea；　vomiting；　sexual　excitement；　flatulence；　syncope；　dysuria；　watchfulness；　lethargy；　even　death　itself；　were　cited　by　them　as　the　consequences　of　being　bitten　by　venomous　spiders；　and　they　made　little　distinction　as　to　their　kinds。　　To　these　symptoms　we　may　add　the　strange　rumour；　repeated　throughout　the　middle　ages；　that　persons　who　were　bitten；　ejected　by　the　bowels　and　kidneys；　and　even　by　vomiting；　substances　resembling　a　spider's　web。
