yeah, Brian Aldiss wrote another work - much longer than "Doomed king" although this one much more interesting personally due to subject ; - inspired by his visits and again few impressive frescos. It is the novel "Barefoot in the head" from 1969... don't own it, did i read it maybe yes almost 30 years ago seem to remember some parts when i looked in English original which i will order etc. Totally forgotten as work by me, until some refreshing and that it was Brian who wrote it ;
from English review:
Psychedelic chemicals, the fruits of the Acid Head War, have turned Europe into a randomised freak-out. Charteris, finding himself taken up as a cult Messiah, believes this imposed image of himself. When he realises that the New Order can only think in terms of old stereotypes, and that in consequence he will probably be crucified, he shakes free of the delusions..

yeas, Brian that is Europe alright

...why is it related to his visits and 3 meter Dusciano ) - well main protagonist is Serb, only boyhood was in Serbia then moved in Italy - Europe is post apocalyptic as mentioned and he moves to England where it becomes some cult leader, don't know details nor interesting to me as "Doomed king" as subject..... to put my own words in review he moves to England as Brian put "He wanted English girls. He had never even known one but, since his earliest days, he had longed for all things English...etc etc"

...to make it humoristic, but scandalous, also Brian's words: "...trying to estimate whether her knickers would be clean or not He was fastidious. Italian girls generally washed more scrupulously than Serbian girls. Bright legs flashing behind torn windscreen." Scandal by Brian... and so on, book from 1969 but in a way some parts are good predictions

...also he wrote things like after arriving in England he finds nation more of mulates and mixed than what he anticipated as some northern country etc. Maybe was true how things looked like from outside in 1969 before the era of mass media, TV and internet - today we all know how some countries look like and similar, so i'm fictionally to move to England i finish with Turk or cute Arab girl etc... but written in 1969 again it had some things like possible wievs like Brian expessed through his characters...
from medievalist point of view Brian named protagonist, Serb, Colin Charteris - giving him originally Scottish last name even one Scot noble from wars with England (again in same time of Dushan's rule) was Charteris and died in battle with English... so generally maybe more traces of Dushan's fresco in Brian's mind, if true that inspired few works, more than great effect

...some trivia, Scottish king David II, Bruce, ruled officially from 1331 (as Dushan) and died in 1371 (as Dushan's son and last Nemanide) trivial but interesting years...
totally different subject i touched, some sources say that Israeli ambassador to Croatia - praising Croatia for being among few that voted against some Arab resolution, we were "abssent" (i.e. yellow in vote) all other ex-Yugosarm states voted for resolution of total unimportance - and he said "Serbs were lucky to be able to go to Serbia, nobody wants to accept Palestinians"... so i guess than we are Arabs of the "Baklavas" in some heads, simplified... Albanian representative in the UN, by Italian media, said before "what Israelis do is genocide like in Srebrenica" ; and so on and on, and on. Terror, haha... Why saying again is how people like to compare things that historically (history is important) uncomparable often having just one idea of own victimisation as truth... dislike it and never made any comparisons on any world (or regional) crisis - ex Yugosarma (it wa fully recognized state, people forget that) is not like Ukraine and Russia nor is same as Arab-Jews (and all atheist Israelis) it is not same as ww2 etc. Every has own history and different political background.... but that is world we live in, without any even try to be consistent - so in Europe we can have situation where one nation can "self-determinate" twice (and once have 2 voices in some fictional unity) and there are historical nations of milions that still can't get own statehood nor voice at all, without naming one i mentioned above

(as said humoristically, it is on people to decide)...it is like that, Europe only. Of course if in name of "new order" we are forced to have English girls for example, it is disgusting....

(joking with Brian) ...have fun, always satire and truth in my words, but generally what i offered as subject is some medieval topics and how we can reconstruct some events without sources which are dubious or incosistent or not present at all... how we evoluted in "Arabs or Israelis" in some uneducated heads is not important as well as Kosano anymore (i understand the world, what to do with 2 mils of Albanians even though land is obviously named by Serb word and that it was historical part of Serbia etc etc) ...we annexed it from Turkey, it belongs to Turkey ) and we all, like Brian's protagonist, reached level of understanding that only Uranus there is future
have fun again, join with some interestings about David the Bruce for example and how he compares to Dusciano of own time, mind that he was probably under 2 meters

personally can say that "Doomed king" touching Vukashin who is not reconstructed till today in our history is more relaxing and fun than other work of his and many other subjects, only wanted to say that comparisons are often bad in political sense... that much from me, maybe for longer time in this thread - if some medieval curiosity, always join me to look at some events...
