Note
This hymnal appears to have been published in honor of the Emperor, Haile Selassie I:
በግርማዊ ቀዳማዊ ኃይለ ሥላሲ ንጉሠ ነገሥት ዘኢትዮጵያ በ፳፱ኛው ዘመን መንግሥት በንግድ ማቀማያ ቤት ታተመ።
አዲስ አበባ ፲፱፻፶፭ ዓ፡ም።
- There may be a problem with the transcribed numerals (29th anniversary [?] in 1962/63 A.D.?). Haile Selassie was crowned Emperor of Ethiopia in November 1930.
Question
- What’s the relationship between this hymnal and Səbhat läʼamlak [ስብሐት ለአምላክ, Praise be to God]. 3rd edition, new layout. Addis Ababa: Commercial Printing Press, 1962/63 (1955 A.M.)?
