GOTHS

"Libussa, Queen of the Goths"

German historian Gobelinus Persona (1358 – 1421) from Westphalia, in his Cosmodromium wrote: "Slavs that is Vandals, live across the Elbe. 

Those in neighboring lands, Cracovia, Polonia, Bohemia, and Sclavonia, speak Gothic, that is Sclavonic."

On picture: "Libussa Goth. Reg." ("Libussa, Queen of the Goths") from Promptuarii Iconum Insigniorum (1553)

Libuše, Libussa or, historically Lubossa, is a legendary ancestor of the Přemyslid dynasty and the Czech people as a whole. According to legend, she was the youngest but wisest of three sisters, who became queen after their father died; she married a ploughman, Přemysl with whom she founded the Přemyslid dynasty, and prophesied and founded the city of Prague in the 8th century. 

Legend: Libuše is said to have been the youngest daughter of the equally mythical Czech ruler Krok (Duke Krok). 

Historian Enea Silvio Piccolomini (1405-1464.) Historia Bohemica , Vinko Pribojevic (15th-1532.) "The Glory of the Slavs", Jan Dubravius (1486–1553) in chronicle Historia regni Bohemia 1552. and all other Czech and Polish historians( 15th-19th) write that Czech and Lech (legendary founder of Czech and Poland) came with his people came from the Dalmatian province of Croatia in the 7th century.

In Russian Nestor's Chronicle (Saint Nestor the Chronicler 1056 – 1114) “The ancestors of the Slavs came from the Danube Basin into the land of Novgorod.”

"Dacia: Land of Transylvania, Cornerstone of Ancient Eastern Europe"

author Ion Grumeza

Acording to Herodot Sarmats, Scythians, Tribali and Geti are all people living north of Macedonia including Dacians are Trachians.

Strabon writes that Macedonians consider Getae Trachian tribe that lives on the north side of Donau, same as Mezians and those are also Trachians and that these two are identical.

He also says that that their language, Getae and Mesians was the same.

Cassius Dio ,roma historian writes that language of Getae and Mesia and Dacians was the same.

"Scythians and Greeks"

Ellis Hovell Minns

Getae were also Carpi or Carpiani (Ptolomei) between the Tyras and Ister with town Harpis on the coast. Niederle suggestes they were Slavs, the same as the enigmatical Khorvate or Croats.

"Pausanias's Description of Greece"

Pausanias and James George Frazer,page 100

Getae were the Slavs and Bulgarians

"Whose love of which country? : composite states, national histories and patriotic discourses in early modern East Central Europe"

authors; Balázs Trencsényi and Márton Zászkaliczky

Pribivojevic relaying on Strabo; Trachians spoke the same language as Mysians,
Roman acording to Appian taught that Mysians are Illyrians and that Thracian and Illyrian language was the same too.
Getae or Goths used the same language as Mysians and Dacians - by Strabo
Pribivojevic draws the conclusion that Mysians ,Illyrians, Dacians and Getae were descendants of Tracians and thus of Thyras, son of Japeth, son of Noah. (his conclusion is hasted, there were older tribes on Helm already but this one fits with church dogma)
