He was a witness to an act of fealty to Filippo Maria in Milan on 5 November 1414, and we don't see him again until 17 February 1416 in Milan, when is a witness to an extension of Filippo Maria's truce with the Marquis of Monferrato.
Not sure if you've come across this work before, but decent chunks of it scanned on Google - 88f especially interesting for plenty of details involving a dice board game. Didn't see Marziano mentioned unfortunately, although plenty of details on the window of time that interests you at the council.

Also, apparently a top ally of Sigismund's machinations at the Council were the Archbishop of Milan, Bartolomeo de la Capra, representing the "Italian nation", although that dates from 1417 (Phillip H. Stump, The Reforms of the Council of Constance (1414-1418, 1994: 33).

I persecuted the word "Mailand" in the 3 Richental editions A-K-G. I attempted to find something about Marziano da Tortona. The result was negative. The only Milanese person in the Richental text is an archbishop of Milan "Niclaus", but the real archbishop of the time was another person.

Richental to the accusation on Jan Hus. A "Niclaus", archbishop of Milan, is mentioned as an active part. The current archbishop of Milan is noted as "Bartolommeo Capra (1414–1433)" https://en.wikipedia.org/wiki/Roman_Cat ... e_of_Milan The extant Richental versions are all written at a later date, so name errors are said to be not rare. Italian wiki has a biography to Bartolommeo Capra:
https://it.wikipedia.org/wiki/Bartolomeo_della_Capra
Arcivescovo di Milano - I primi difficili anni (1411-1417)
Il 7 febbraio 1414, dopo la morte di Francesco Crippa, Bartolomeo della Capra venne confermato ufficialmente arcivescovo dall'antipapa Giovanni XXIII (questi temeva che il Capra, per la sua ambiguità, fosse favorevole invece al papa romano, Gregorio XII). Nonostante tutto, Giovanni II Visconti si oppose al suo ingresso in Milano, obbligando il Capra a rimanere fuori Milano. Il problema fu risolto con la deposizione di Giovanni XXIII in occasione del Concilio di Costanza, il quale confermò (nella XIV sessione del 4 luglio 1417) Bartolomeo Capra quale legittimo arcivescovo e depose il rivale Giovanni Visconti[5]. Il suo ruolo al Concilio di Costanza, inoltre, fu assai rilevante. Eletto, insieme al cardinale Giordano Orsini, Commissario Generale del Concilio, il Capra si mise in mostra per le sue abilità politiche e diplomatiche[6]. Confermato poi quale legittimo arcivescovo di Milano, il Capra divenne anche l'ambasciatore ufficiale del duca Filippo Maria Visconti[6]. Ebbe, inoltre, un ruolo rilevante nel processo contro Giovanni XXIII, in quanto rilasciò una propria dichiarazione contro il papa pisano, accusandolo dei seguenti misfatti che vennero annotati nei L d'accusa:
«Et audivit, quod cognovit Bononie tres sorores et unum masculum fratrem earum et matrem, et finaliter per volgares fuit dictum, si pater affuisset, similiter partem suam ab eo reportaret»
«E ha udito che a Bologna avesse avuto rapporti con tre sorelle, e con un loro fratello maschio, e con la madre, e alla fin fine da parte della gente del popolo era stato detto che se fosse stato presente anche il padre, similmente anche questi si sarebbe preso da lui la sua parte!»
(Bartolomeo Capra, Acta Consilli Costanciensis, 16 maggio 1415)

Missioni diplomatiche e attività pastorale
Il Capra poté quindi, con il decreto conciliare, prendere possesso definitivo della cattedra ambrosiana, divenendo uno dei più importanti consiglieri politici e religiosi di Filippo Maria Visconti e dell'imperatore Sigismondo, viaggiando per tutta Europa. È ovvio immaginare che, preso dalla frenesia della politica internazionale, l'arcivescovo si curò ben poco delle questioni religiose e pastorali della sua arcidiocesi: si affidò soprattutto al suo vicario, l'abate Beteto Trivulzio[7]. Alcune date rilevanti che lo videro partecipe in prima persona di importanti eventi: accolse Martino V, di ritorno da Costanza, a Milano, ove procedette alla consacrazione dell'altare del Duomo (16 ottobre 1418); incoronò Sigismondo come re d'Italia (25 novembre 1431) .....
*************

A-version Richental 156 ... the topics are Jan Hus and the accusations against him. Jan Hus is still living and was later burned at 6th of July 1415.

A lot of nobility on 2000 horses accompany the start of this journey (likely it's still an adventurous attempt to cross the Alps so early in the year). Georg himself had 100 horses, when he appeared in Konstanz.

Thanks for looking! I can't get the regesta.imperii.de link to work.

Marziano would probably not be Marziano "da Tortona," but more "Marziano Rampini" (Martianus Rampinus) with some form of Sancto Alosio. "Alosio" is usally taken to be from Louis, often Aloysio, Aloxio, Allosio, etc. Sanctus Aloysius. (H)Enrico Rampini was bishop of Tortona in 1415.

Maybe the Germans would take his name to be Martin.

If Marciano indeed was in Constance ...
... then one could ask, when he traveled. John XXIII wished to start at 1414 November 1, the real start had been at 1414 november 5. Then Martiano was still in Milan.
The most interesting date is 5th/7th day of May, cause then the Italian groups definitely were there.

Chrysolares died 15th of April 1415 (buried 25th April) ... https://www.foto-schuhmacher.de/i/beise ... loras.html
Earlier (old text) I noted:
"1400: The great Greek scholar Manuel Chrysolares, after teaching 3 years in Florence from 1397 - 1400, resides and teaches in Pavia with the great Visconti library, probably occasionally also in Milan and other surrounding cities from 1400 - 1403. It seems, that the enthusiastic Uberto becomes his major follower. In 1402 Uberto works with Manuel Chrysolares on a translation of Platon's Republic, the text is finished later by Pier Candido Decembrio in 1439 (or earlier ?). Uberto and Chrysolares communicate via letters in the later time till the death of Chrysolares (died 1415 in Constance as messenger of the Greek emperor).
1402: Giangaleazzo dies and the political change causes much trouble in Milan. Probably as one of the results of this change Chrysolares leaves Pavia."
Chrysolares once had been in Milan. Is it possible, that there was a relation between Martiano and Chrysolares? It comes to my mind, that 1403 is the year, when Michelino painted the Visconti-genealogy. Had this something to do with the condition, that Chrysolares was in Pavia/Milan? I remember, that Ross stated once, that the content of the genealogy (with its Greek connections) was already prepared otherwise. Nonetheless the actual genealogy project might have been inspired by the presence of Chrysolares.

Treccani.it ...http://www.treccani.it/enciclopedia/mar ... ntesca%29/
Le fonti della biografia di M., a parte i documenti della cancelleria viscontea che testimoniano la sua qualità e attività di segretario ducale, si riducono ad alcuni accenni contenuti nella vita di Filippo Maria Visconti del Decembrio e all'elogio funebre dettato da Gasparino Barzizza. Studiò a Tortona, poi a Pavia, a Padova, a Firenze.
There is the possibility, that Marzino was in Pavia during 1401-1403.

From the biography of Carlo Malatesta di Rimini
Extract of https://condottieridiventura.it/carlo-m ... di-rimini/
(1408) Nov. in Romagna
He hosts in Rimini Pope Gregory XII who from Siena, no longer safe for the pontiff, moved to his city. The Malatesta returns to Milan and makes an agreement with the castellans of Porta Giovia, rebels against the ducal policy, with the intermediation of Bernardo della Serra, governor of Asti on behalf of the Duke of Orleans.

1409 Feb. in Romagna
He is engaged in Cesena in talks with the cardinal legate, Baldassarre Cossa, representative of the antipope Alexander V elected by the Council of Pisa. He was forced to leave Milan due to the prevalence of the Ghibelline faction.

1409 Apr. in Brescia - Milan Lombardy Tuscany Romagna
He still faces Facino Cane with his brother Pandolfo; on Easter day he clashes with opponents in Rovegnate. The following day he reconciles with the enemy and together they prevent Milan from being occupied by the French of Boucicaut, called in the meantime by the Duke Giovanni Maria Visconti. Malatesta goes to the Council of Pisa and defends the cause of Gregory XII, which he soon reaches in Rimini.
Ross ... when is the precise date, when Marciana da Tortona leaves his occupation for Gregory XII?

After 4 May 1408 and before 2 Feburary 1409.

On 4 May in Lucca, Gregory authorized the rule for a an order of hermits that Marziano was a witness to. Shortly after in this month, Gregory created new cardinals. Since he had sworn an oath at his election, which included the promise not to create new cardinals, many of those present decided to break with him and left the city. This led to the council of PIsa the next year, which elected a new pope, without either Gregory or Benedict XIII (Avignon) present. Gregory himself left Lucca in July 1408 (check dates) and quickly ended up in Rimini.

Marziano is next recorded in Tortona on 2 February 1409, where he is the representative of the Rampini family, among five Ghibelline families who form a pro-Visconti league, against the Genovese Guelphs.

So I think that Marziano must have been among those who left Gregory in May or June of 1408. The stiuation in his homeland was urgent, and he had to bring his diplomatic knowledge.

Gregory XII itinerary in 1407-1409 -

Gregory XII left Rome 9 August 1407
In Viterbo 11-31 August
In Siena 4 September 1407-23 January 1408
In Lucca 28 January-14 July 1408
In Siena 19 July-3 November (26 October?)
In Rimini. Cividale del Friuli 26 May 1409.

Gherardo Ortalli, "Gregorio XII, papa" in Dizionario biografico degli Italiani (2002) https://www.treccani.it/enciclopedia/pa ... iografico)
Per G. XII la situazione non era migliore; l'insoddisfazione nei suoi confronti giunse al punto di rottura quando il 9 maggio 1408, mentre si trovava ancora a Lucca, per rafforzare la sua posizione volle creare quattro nuovi cardinali scelti fra le persone a lui più vicine, contravvenendo con ciò pure all'impegno di non procedere a nuove nomine che potevano rendere più complesso il cammino verso l'unità. La reazione del S. Collegio di obbedienza romana fu immediata e l'11 maggio la maggioranza dei suoi cardinali abbandonò G. XII ritirandosi a Pisa.
Tra gli eletti del 9 maggio vi erano anche due nipoti di G. XII: Antonio Correr e Gabriele Condulmer (divenuto poi papa nel 1431 col nome di Eugenio IV).
In ogni caso le nomine cardinalizie del maggio 1408 parvero andare oltre il limite del tollerabile e finirono per avere contraccolpi davvero pesanti. Per rinsaldare una situazione che andava facendosi sempre più critica G. XII nominò altri nove cardinali nel settembre del 1408, ma la cosa risultò un nuovo segnale di debolezza piuttosto che di maggiore forza.

Intanto le insoddisfazioni dei prelati delle due obbedienze si combinavano in un impegno comune che avrebbe portato al concilio di Pisa. Ai cardinali che avevano abbandonato in maggio G. XII si unirono in giugno quelli che avevano lasciato Benedetto XIII e insieme concordarono sulla necessità di un concilio che ponesse fine allo scisma, impegnandosi in un notevole sforzo per la sua migliore riuscita.
"For Gregory XII the situation was no better [than Benedict XIII in Avignon]; the dissatisfaction with him reached the breaking point when, on 9 May 1408, while he was still in Lucca, in order to strengthen his position he decided to create four new cardinals chosen from among the people closest to him, in so doing also contravening the commitment not to make new appointments that could make the path towards unity more difficult. The reaction of the Holy College of Roman obedience was immediate and on 11 May the majority of its cardinals abandoned Gregory XII and withdrew to Pisa.
"Among those elected on 9th May there were also two nephews of Gregory XII: Antonio Correr and Gabriele Condulmer (who later became Pope in 1431 under the name of Eugenio IV).
"In any case, the cardinals' appointments of May 1408 seemed to go beyond the tolerable limit and ended up having very serious repercussions. In order to consolidate a situation that was becoming increasingly critical, Gregory XII appointed nine more cardinals in September 1408, but this was a new sign of weakness rather than greater strength.
"In the meantime the dissatisfactions of the prelates of the two obediences were combined in a common commitment that would lead to the Council of Pisa. The cardinals who had left Gregory XII in May were joined in June by those who had left Benedict XIII, and together they agreed on the need for a council that would put an end to the schism, committing themselves in a considerable effort for its better success."

Re: Council of Constance

Thanks, I had detected these dates already in the Marziano thread in the post from 28th of March 2020.
Are there any other factual dates with the direct participation of Marciano before May 1408? Or are the related activities (studies in various cities, birth date in the family chart) all organized by later reports?

The development of a third pope with Milanese roots (Pietro of Candia as Alexander V, actually with a birth at the island of Crete, Greece, but already a long time in Milan since 1386 or even earlier) during the council of Pisa (1409). Alexander died at 3./4. May 1410, possibly poisoned by Baldassare Cosssa.
English wiki to Gregory XII describes the scene of 4th of May 1408:
The cardinals of Gregory XII openly showed their dissatisfaction at this manoeuvring and gave signs of their intention to abandon him. On 4 May 1408, Gregory XII convened his cardinals at Lucca and ordered them not to leave the city under any pretext. He tried to supplement his following by creating four of his Corraro nephews cardinals – including the future Pope Eugene IV, despite his promise in the conclave that he would create no new cardinals. Seven of the cardinals secretly left Lucca and negotiated with the cardinals of Benedict XIII concerning the convocation of a general council by them, at which both pontiffs should be deposed and a new one elected. Consequently, they convoked the Council of Pisa and invited both pontiffs to be present. Neither Gregory XII nor Benedict XIII appeared.
It's strange, that the date 4th of May appears twice.
Pietro of Candia was in Prague in 1395 and traded the duke title for Giangaleazzo against a high sum of money. The success in this matter caused indrectly the abdication of the Roman king Wenzel in the year 1400, the German nobility.
https://karolinum.cz/data/clanek/3130/H ... 23-130.pdf ... see sentence "(Uberto) Decembrio followed the bishop (= Pietro da Candia, here Peter Filargis of Candia) during his diplomatic mission to Prague seeking the title of duke for Gian Galeazzo Visconti (1351-1402)" at the first page. At the second page is the following snippet:

Uberto Decembrio was father of Pier Candid Decembrio, who reported the existence of the Michelino deck at the court of Filippo Maria Visconti (Pier Candid got his rare name from Pietro da Candia, which expresses, that Uberto Decembrio and Pietro da Candia had a close friendship with each other.
Possibly Uberto stayed 3 years, possibly also Pietro da Candia stayed 3 years.
Here is a biography of a very useful website about cardinal-biographies, which had disappeared. One still can find it at archive.org. Pietro da Candia had this text

I found some details, which aren't given in other biographies, for instance his presence in Russia and possibly also a presence in Bohemia before 1394/95. As he was also active in England and France he had indeed advanced international experiences.
