Some critics[1][5] have challenged the view that the Sulpicia poems were authored by a woman; Hubbard suggests that it is unlikely for a roman girl to publicly write about sexual matters and make rebellious declarations to her guardians, while Habinek and Holzberg both suggest that the poems are too sophisticated.[6][5] In an overview of Sulpician criticism, Alison Keith described the logic of Hubbard's article as "tortuous" and also highlights problems in Holzberg and Habinek's attempts to efface female authorship.[7] In contrast, Hallett argues for increasing the numbers of poems attributed to Sulpicia to include poems 8-12 from the Corpus Tibullianum, which had previously been attributed to an amicus Sulpiciae (friend of Sulpicia).[8]
