The Synagogue Of Maroussi
 in the Royalton Hotel .
Caresse Crosby (born Mary Phelps Jacob, 1891-1970) was a writer, editor, and co-founder of Black Sun Press. As a literary socialite in Paris in the 1920s and ‘30s, she naturally befriended Henry when he arrived on the Paris scene in 1933 . Crosby owned several homes , including one in Bowling Green, Virginia, and an apartment she kept in midtown Manhattan. In February 1940, Anais Nin visited Caresse in the apartment at 137 East 54th Street, at Lexington; both women were living in New York at the time. Anais told Caresse that the apartment was exactly something Henry would like; not long afterwards, Caresse informed Anais that there was “a bachelor apartment for rent in the same house. It was just what he wanted, a large room to work in, peaceful and secluded, because the windows gave on a back yard” .
Henry’s furnished apartment at 137 East 54th Street became the scene of much proactive writing, starting in March 1940. Here, “overlooking a synagogue,” Miller wrote, amongst other things, the short novels The World Of Sex and Quiet Days in Clichy, as well as the essay “Reflections on Writing” . By May 1940, he was also 80 pages into The Colossus Of Maroussi, which he would complete that summer at Crosby’s manor at Bowling Green, VA.

The apartment was located at East 54th and Lexington; near the south-east corner, as far as I can tell. There is barely an internet presence for this address, even with a reverse address search. It may have been a small building that has since been torn down to make way for the apartment building at 135 E. 54th, which was constructed in 1949  or possibly the big, modern glass buildings that today appear to domainate that corner.
Henry was keeping his 54th Street address a secret. In a March 4th letter to his publisher James Laughlin, he only stated that he was “near" the Gotham Book Mart, which is where he was having all of his mail directed . Gotham was located at 41 West 47th Street, and was only about 10-11 blocks away from Henry’s temporary residence at Lexington.
Much closer, just north up the Lexington block from East 54th, was New York’s oldest synagogue in continuous use . Central Synagogue was—and still is—located at 652 Lexington Avenue (at 55th), where it has stood since 1872. By using the amazing street-level view of New York on Google Maps, you can really get a sense of how close the synagogue is to Henry’s apartment by taking a virtual walk. I can't be sure that Henry had a direct view from his apartment. In Jay Martin’s Always Merry And Bright, he states that Henry’s writing window overlooked a courtyard (p.369), and Anais Nin, quoted above , states that Henry’s window faced a back yard; in my mind, a back courtyard would face south, away from the synagogue. And of course, Henry himself wrote that his room overlooked the synagogue. I can’t quite figure out the logistics. Perhaps it was not in his view as he wrote.
What, then, is the significance of mentioning this synagogue in relation to writing Colossus Of Maroussi? Was Henry simply trying to embellish a degree of spiritual romanticism to the experience of writing it by making a connection with its proximity—architecture as muse? For someone who found New York so depressing, the sight of something “exotic,” something reflecting the “spiritual” and representing the “Other” may have offered Henry some mental refuge just by looking at it. His appreciation for synagogues is apparent on page 60 of the hardcover edition of My Life And Times (1971) is an undated, handwritten list of places in the world “where mysterious things happened to me”; in the third column, Henry references four synagogues, at Prague, Toledo [?], Seville and “Loop – Chicago” (the latter being the location of a stained-glass mural created by his artist friend Abraham Rattner).
There are only two minor references to anything Judaic in Colossus (pages 202 + 219), so the synagogue had little if any direct influence on the content of his book. Unfortunately, I have nothing more to support the claim that he wrote inside the synagogue, although the interior [seen below] is quite large and has upper-floor galleries in which I suppose Henry could have easily sat inconspicuously with a notebook. “The whole book came effortlessly,” wrote Miller, “often with tears streaming down my face—tears of joy and tears of sorrow” .
This interior view of Central Synagogue was found on the NYC Architecture website.
Although Miller completed enough of Colossus Of Maroussi by the end of June to submit it for consideration to James Laughlin of New Directions (who passed on it in writing on July 3rd, 1940 ), Henry continued to expand on it. It was completed in August 1940, while Henry was staying at Craesse Crosby’s estate in Bowling Green, Virginia . Colossus was first published by Colt Press (San Francisco) in October 1941 .
The Central Synagogue was badly damaged in a fire in 1998, but has been restored and continues to thrive at Lexington and 55th.
