Ostrogoths, Vandals.
Tribes of Veneti Slavs called Vandals, have "vandalized" Rome, destroyed the Roman empire and finally through France and Spain travelled to Africa where they have settled on the shores of the Mediterrannean in today's Tunisia and Libya. The graphic depicts a Veneti-Vandal symbol for 'the hands of god'.

The original home of the Vandals (and Ostrogoths) was the area between southern Poland and northern Serbia. The migration of Vandal Slavic warriors from central Europe into Africa has made all Slavs more susceptible to subsequent invasions both from the west and from the east and marks the beginning of the break-up of the Veneti empire.
About the Ostrogoth (Vandal) culture we find very little concrete informaiton only various guesses, mostly by Germanic scientists who assume, because of the Roman name "Ostrogoths" that they were in some ways related to "Goths and Visigoths". The problem lies in the Roman names, since to the Romans all the tribes who were not speaking Latin were "Goths" and then they subdivided them into various subgroups such as Ostrogoths (Slavs). Visigoths, etc.
In a similar way the Greeks called all tribes and peoples which were non-greek speaking "Barbarians", and the Slavs called non-Slavic speaking tribes (specifically Germanic tribes) as "Nemtsi" which means "the dumb ones".
To find the proof that Ostrogoths (including Vandals) were Slavs we just have to look at the typically Slavic names of their leaders. While the language of the Ostrogoths is still shrouded in mystery (maybe on purpose since Germanic researchers don't want to admit that they were Slavs), and since also their writing is also shrouded in a similar "mystery", one thing that is not shouded and which had remained to this day are the Slavic names of their leaders. Here are just a few names of the leaders and of their dynasties: Valamir, Theodemir, Theodoric, Athalaric, Eraric, Geiseric, Gunderic, Hilderic, Gelimir, etc. Furthermore the name Vandals is no doubt related to the Venden (Wenden) which are aboriginal Slavic population living to this day in central Germany. To Slavic researchers the Venden (Wenden) are known as Sorbs.
What is most interesting are the Roman sources which claim that Ostrogoths (Slavs) have come from Phrygia, whic only confirms the previously stated information that Phrygians (also called Brigs) were Slavs. So while Visigoths were most likely Germanic tribes, Ostrogoths were Slavs. The confusion comes only from the common name of "Goths" given to all by the Romans.
