En deux parties distinctes mais complémentaires, ce travail se présente comme le parallèle dans le domaine grammatical des recherches menées sur l’archaïsme dans la rhétorique et la littérature latines. Nous analysons tout d’abord la manière dont les grammairiens latins, de Varron à Priscien, considèrent ce phénomène, dans le cadre de la définition de la langue latine correcte (Latinitas). Les questions du recours aux archaïsmes dans l’usage et de l’autorité des auteurs littéraires anciens, telles que l’on peut les retrouver dans les textes du corpus des grammatici Latini, sont au centre de notre étude. Nous proposons ensuite pour la première fois une édition avec traduction et commentaire critique des fragments de Flavius Caper, grammairien de la fin du IIe siècle après J.-C. : cette époque marquant la diffusion d’une mouvance stylistique et littéraire archaïsante, l’examen du point de vue d’un grammairien sur la langue latine contemporaine se révèle primordial pour comprendre l’évolution de la pensée linguistique antique. L'édition des fragments du De Latinitate et du De dubiis generibus de Caper nous donne par ailleurs l'occasion de réfléchir aux problèmes des sources et de la transmission des textes, aussi bien grammaticaux que littéraires, ainsi que d'effectuer un commentaire analytique sur un auteur à tort négligé et qui, par sa réception, a joué un rôle de premier plan dans la tradition artigraphique tardo-antique. / Organised in two complementary parts, the present research follows up, in the grammatical tradition, on other studies led on archaism in the fields of Latin rhetoric and literature. The first part deals with the way in which Latin grammarians, from Varro to Priscian, apprehend the notion of archaism, within the definition of what they consider to be the correct Latin language (Latinitas). The study is focused on both the main issues of the use of archaisms in the current usage, and the ancient poets’ and prose writers’ authority, as noticeable in the grammatici Latini corpus. In the second part, an edition of Flavius Caper’s grammatical fragments, with a French translation and critical commentary, is proposed for the first time. Caper is a scholar of the end of the 2nd century AD, an era especially known for the diffusion in the literary circles of an archaizing stylistic tendency. Consequently, examining the point of view of a grammarian on the linguistic usage of his time appears crucial to understanding the evolution of linguistic thought in Antiquity. The edition of Caper’s fragmentary De Latinitate and De dubiis generibus gives us the opportunity to reflect upon sources and transmission of grammatical and literary texts. Finally, the comments made on the work of a still unrecognised scholar should highlight the importance of his treatises in the late antique grammatical tradition.

This thesis is one of the first works in the Czech language dealing with the personality and work of Marcus Cornelius Fronto, Roman rhetor of 2. century A. D. and teacher of Marcus Aurelius. After the palimpsest with the correspondence of Fronto was found in early 19th century, the reputation of this man suffered greatly. The man had been seen for many decades as superficial and flat archaisator, whose letters have no or only very little value for us. The aim of this tesis is to examinate the most problematical questions connected with Fronto, firstly his attitude to philosophy and the opinion, that archaism is the main and ubiquitous characteristic of his style. This theoretical treatise is accompanied with translation of several selected texts.

In this thesis we explore the period of renewal that Athens experienced during the second century AD. This century saw Athens at the peak of her cultural prominence in the Roman Empire: the city was the centre of the League of the Panhellenion and hosted a vibrant sophistic scene that attracted orators from across the Greek world, developments which were ideologically fuelled by contemporary conceptions of Classical Athens. While this Athenian 'golden age' is a standard feature of scholarship on Greek culture under Rome, my thesis delves further to explore the renewal of the urban and rural landscapes at this time and the relationship between that process and constructions of Athenian identity. We approach the renewal of second-century Athens through four lenses: past and present in the Ilissos area; the rhetoric of the Panhellenion; elite conflict and competition; and the character of the Attic countryside. My central conclusions are as follows: 1. The renewal of Athens was effected chiefly by Hadrian and the Athenian elite and was modelled on an ideal Athenian past, strategically manipulated to suit present purpose; the attractions of the fifth-century golden age for this programme of renewal meant that politically contentious history of radical democracy and aggressive imperialism had to be safely rewritten. 2. Athens and Attica retained their uniquely integrated character in the second century. Rural Attica was the subject of a powerful sacro-idyllic ideology and played a vital role in concepts of Athenian identity, while simultaneously serving as a functional landscape of production and inhabitation. 3. The true socio-economic importance of the Attic countryside as a settled and productive landscape should be investigated without unduly privileging the limited evidence from survey, and by combining all available sources, both literary and documentary, with attention to their content, cultural context and ideological relevance.
