I heard that the origin of espresso macchiato was so that the bartender knew that a particular coffee in a line of coffees was different – hotter or stronger or decaf – so it was marked – macchiato – with a tiny bit of milk foam. The term has been around for a long time apparently, so some say the milk would not have been textured or foamed, as the term predates espresso machines – but of course even heating milk in a saucepan makes it go a bit foamy. So it was to mark out that coffee, not to alter its taste. Any thoughts? Obviously a latte macchiato is a totally different drink and has resulted in considerable confusion.
I would like to add that at the start of the Viking Age, there was a common culture shared by the various peoples of Scandinavia. The archeological record shows us a cultural consistency between settlements in Denmark, Norway, and Sweden. Among these was Gotland, which as you said is not Sweden, but it did in the 8th century fit the common mold. From there, exiles formed the Grobin colony (in modern day Latvia), and eventually the Ladoga colony, all of which, from an archeological standpoint, can be described as Norse. These, I think, are the main evidences we have to support that the Rus were Norse.
