H. P. Lovecraft [SEP] Early life and family tragedies
In his old age he helped raise the young H. P. Lovecraft and educated him not only in the classics, but also in original weird tales of "winged horrors" and "deep, low, moaning sounds" which he created for his grandchild's entertainment. The exact sources of Phillips' weird tales have not been identified. Lovecraft himself guessed that they originated from classic Gothic novelists like Ann Radcliffe, Matthew Lewis, and Charles Maturin. It was in this period that Lovecraft was introduced to some of his earliest literary influences such as "The Rime of the Ancient Mariner" illustrated by Gustave Doré, "One Thousand and One Nights", a gift from his mother, Thomas Bulfinch's "Age of Fable" and Ovid's "Metamorphoses".
