To me, Umadevi has remained a mystery. Only recently (in Toronto) I discovered a couple of website (http://www.theohistory.org/description-of-issues/descript_of_issues_v5.html) that not only describes her work in some detail but also mentions about her friendship with Harischandra. The earlier link to her name is another one.
A couple of years ago, thanks to an opportunity provided to me by Mira Vaidya – my aunt and Hariscandra’s daughter – I wrote an article on Hariscandra’s knowledge and understanding of the region for a book edited by Niranjan Bhagat, an eminent Gujarati poet to commemorate Harischandra’s 100th birth anniversary.
Harischandra’s enormous library comprised a large section on books about East Europe in general and Poland in particular. Besides writing path-breaking poetry and introducing Gujarati literature to the works of European poets, and in general quietly revolutionizing Gujarati literature, Harischandra’s only work on the geo-political situation of the early 20th century was Joesf Pilsudski’s biography in Gujarati.
An aside: For some reason, whenever I've tried to visualize Taras Bulba, actor Prithviraj Kapoor’s face comes to my mind. Hollywood made Taras Bulba in 1962 and Yul Brynner enacted the role of the Cossack chieftain. I think Prithviraj Kapoor would have made a better Taras Bulba.
